Ross Brawn should be firing on all cylinders as he returns to the pitwall in Monaco this weekend.

Mercedes’ team principal sat out the recent Spanish grand prix due to illness, but a scarcity of extra information triggered speculation.

One rumour was that he is seriously ill, whilst another was that his absence may in fact be due to his German employer’s high-stakes spat with Bernie Ecclestone.

The latter theory gained traction since Barcelona, with acting team boss Nick Fry taking a much higher than usual profile, including naming Paul di Resta as a possible 2013 successor for Michael Schumacher.

Explaining his absence, Brawn told Bild newspaper: “On the Tuesday before Barcelona I felt unwell so I went to the doctor and then stayed a night in hospital for some tests.

“When I got home, I decided on the advice of doctors to give myself a weekend off, to be sure that I am fit for Monaco,” the Briton said.

Partly because of Brawn’s deputy Fry’s recent comments, and also due to his paltry points tally and his crash with Bruno Senna, rumours about Schumacher’s future have intensified since Spain.

“A lot has been said and written,” acknowledged Brawn, “but we should not forget that we – the team – have let him down in three of the fives races, not delivering the job we should have.

“We must do better,” Brawn, who worked closely with Schumacher during the seven time world champion’s ultra successful Ferrari era, added.

“We saw Michael’s real quality again in the first race, so it’s for that reason that I believe we will see him on the podium this year.”

As for a possible contract extension for the 43-year-old, Brawn insisted: “When the time comes, we will sit down together and talk about the future.

“I’m sure it will become clear very quickly in what direction we will go.”

Felipe Massa has played down reports he is at risk of losing his Ferrari seat soon, insisting he feels fully supported by Ferrari.

The Brazilian has struggled at the wheel of Ferrari’s difficult 2012 car so far, scoring just 2 points compared with his teammate and joint championship leader Fernando Alonso’s 61.

It has triggered speculation the Maranello based team might replace him, also because Ferrari said after Barcelona it is “expecting” Massa to improve “right away”.

Whilst working at Maranello in the driver simulator on Friday, however, Massa insisted he has not been far away from Alonso at recent races.

“I think we must also take into account that, at the moment, Fernando’s driving is amazing: he is on super form, maybe even perfect,” he is quoted as saying in a Ferrari statement.

Asked if he feels the famous Italian team’s support, he added: “Absolutely, yes, I feel the whole team stands by me.

“Obviously, they are not happy with the results and neither am I: we all want to get out of this (situation) and return to normal.

“It’s possible and for sure it’s what I want and I know that with the team’s help we will manage it,” said Massa.

Flavio Briatore could be readying to burst back into formula one.

Germany’s Auto Motor und Sport said the ousted and formerly banned Italian is busily writing regulations for a ‘GP1′ championship.

They could be adopted should the FIA not sign up to the 2013 Concorde Agreement, according to the report.

Apparently, the political rumblings in F1 at present are not limited to the sport’s planned floatation, or Bernie Ecclestone’s spat with Mercedes.

Cost-control is also a buzzword. As reported recently, the vast majority of F1′s teams want the FIA to enshrine cost-cutting in the actual sporting regulations, even to the point of pushing for a once highly-controversial budget cap.

F1 chief executive Ecclestone, however, is not famously close with the FIA’s new president Jean Todt, and according to Auto Motor und Sport he is not convinced that the Paris federation needs to write and control the rules.

Enter Briatore. The German report said Ferrari will be a fan of the former Renault chief’s rumoured regulations, as they steer away from the premium on aerodynamics.

Red Bull is lamenting the limited role that can be played in 2012 by F1′s aerodynamic genius Adrian Newey.

For the past few years, the energy drink owned team has enjoyed its dominance largely because of the airflow magic wrought by Briton Newey.

But in 2012, with reigning back to back world champion Sebastian Vettel just one of the five different winners so far, Pirelli rubber is king.

“I doubt Williams really know why they were so strong,” team boss Christian Horner, referring to Pastor Maldonado’s shock Barcelona pole and win last weekend, is quoted by Germany’s Auto Motor und Sport.

Horner insisted that, rather than the winner being the team with the best overall package at each race, success this season is about “understanding the characteristics of the tyre and the window in which they work”.

“It’s not that the midfield teams have made a quantum leap aerodynamically from last year to this year,” Horner insisted. “But from a performance point of view, this is what they have done.”

The logical conclusion is that aerodynamic cleverness has taken a back seat.

So will Red Bull knock a million or two off Newey’s huge annual retainer?

Horner laughed. “Adrian is not just an aerodynamicist, and aerodynamics are still important anyway. But now it’s about harmonising everything, and these tyres are simply remarkably complex.

“Two races ago Nico Rosberg dominated, but in Spain he was almost lapped. It is very difficult to predict what’s going to happen next — a nightmare for the bookmakers,” he smiled. “A lottery.”

The situation has split F1 into two camps: those who love it, and those who do not.

“It has become like a GP2 championship,” Maldonado, the junior category’s 2010 champion, is quoted by The National newspaper.

“The drivers can make the difference and the teams can still work on the strategy and the car.”

The bizarre situation has left everyone scratching their heads, like Jenson Button.

He can scarcely believe that what looked a championship car – his 2012 McLaren – was beaten in Spain by Shanghai winner Nico Rosberg, who was almost lapped.

“The Red Bulls did a better job at the weekend than us in terms of points, but still they weren’t quick when you compare them to Williams, Sauber, Lotus and Ferrari,” he told PA Sport.

“Five different teams winning five different races, we really don’t know what’s going on, and I think that’s the same up and down the pitlane.”

F1′s next winner could be at the wheel of a black and gold car.

“I think Kimi (Raikkonen) will be the sixth different winner in the sixth race,” said Finnish commentator and former driver Mika Salo, to the MTV3 broadcaster.

Although the results in 2012 have proved impossible to predict so far, many paddock pundits expected Lotus’ E20 to be the car to beat last weekend in Barcelona.

“The big surprise was when Kimi didn’t win,” admitted former Ferrari driver Salo, referring to Pastor Maldonado’s victory for Williams.

Also confident about Lotus’ potential is Raikkonen’s teammate, Romain Grosjean, who finished behind the 2007 world champion last weekend.

“It’s good to be a little disappointed with third and fourth,” he told the French language RMC Sport. “It shows that as a team we are convinced we can win.”

According to the reigning world champion team Red Bull’s drivers, however, there is a downside to this year’s impossible-to-predict F1 landscape.

“Maybe we will see an HRT or a Marussia on pole in Monaco,” world champion Sebastian Vettel said, unenthusiastically and half-seriously.

Mark Webber insists that what has been described as the Pirelli ‘lottery’ might not be a good thing for the sport.

“I don’t know if they (the fans) will get sick of seeing so many different winners,” the Australian told Fox Sports.

“It’s nice to have different winners but also we want rivals.”

More than half of Michael Schumacher’s German compatriots think the seven time world champion will return to retirement at the end of this year.

After three years of retirement, the 43-year-old returned to F1 in 2010 on a three-year Mercedes contract, which runs out in 2012.

SID news agency commissioned the German market research company Promit to carry out a survey as to whether respondents think Schumacher will quit at the end of this year.

55.4 per cent answered yes, while only 26.2 per cent said they think Schumacher should sign on for at least another season.

The winner of a record 91 grands prix has failed to see the chequered flag in three of the five races so far this year, finishing just tenth in both Malaysia and Bahrain.

In contrast, teammate Nico Rosberg’s three top-seven finishes in 2012 included pole and victory in China, netting him 41 points compared with Schumacher’s 2 overall.

“I don’t think we can write him (Schumacher) off yet,” insisted Telegraph correspondent Tom Cary this week.

“His pace hasn’t been bad and he started the season very well. (He) was unlucky in quite a few races, his wheel fell off when he was running second in China and could have had a big haul of points.

“He is making mistakes in wheel-to-wheel racing though. But if he gets a few decent finishes or even wins a race then we could see him continue (in 2013),” added Cary.

Last Sunday proved that Pastor Maldonado is no mere ‘pay driver’.

“If he was a fool, he would not be with us, no matter how much money he brings,” Sir Frank Williams is quoted by Brazil’s Globo Esporte.

Venezuelan Maldonado, whose links to the state owned oil company PDVSA and president Hugo Chavez controversially deliver many millions to Williams’ Oxfordshire based team, became F1′s fifth different winner of 2012 last weekend in Spain.

It has helped him to shake off the ‘pay driver’ insult, Williams insisting he is now a potential world champion instead.

“Without a doubt. He is very fast and makes no mistakes,” the newly 70-year-old Briton said.

Williams does, however, acknowledge that Maldonado’s money was a key factor in the decision to sign him.

“Yes, it was to some extent,” he said. “I don’t deny that. But he’s also a real driver. He fully deserves to be on the team, with or without money.

“The truth is that if you don’t have money, you don’t get to be in formula one,” added Williams.

Team shareholder Toto Wolff agrees: “If you want to race in GP2, you need a few million pounds. So, the drivers need not only to be fast and talented, but able to attract the sponsors.

“So let’s forget this thing about ‘pay drivers’,” he insisted.

Triple world champion Nelson Piquet, however, has some lingering doubts.

He ran Maldonado in his own GP2 team some years ago, and this week recalled a driver who was often “too aggressive” and made too many mistakes.

“We’re not talking about a guy who shone in his youth, like Nico Rosberg,” said the famous Brazilian, “or someone like Lewis Hamilton, who always had everything he needed thanks to Ron Dennis.

“In GP2, when you don’t stand out in your second year, you begin to be doubted. In Maldonado’s case, he only shone in his fourth year.

“Perhaps because of this he only made it to formula one as a paying driver, without having anything special, apparently. He was perceived as just a good pilot, but clearly no Alonso.

“Now he was at the right place at the right time but he still managed to beat Alonso in Spain as well as another world champion, Kimi (Raikkonen). So hats off to him.”

The oddest element of the 2012 season so far is that the unlikeliest of candidates could now be genuine title contenders.

Before the Spanish grand prix weekend, Pastor Maldonado was a commonly derided ‘pay driver’ with 500-1 odds of winning in Barcelona, and just a single point to his name in 2011.

Now, he is F1′s newest pole-getter and race victor, and genuinely regarded as a potential contender for the world championship.

And Dr Helmut Marko, the reigning world champion Red Bull’s motor racing manager, said: “If the Williams really has traction that good, then Maldonado will run rings around everyone in Monte Carlo,” he is quoted by Auto Motor und Sport.

Maldonado travelled straight from Spain to Caracus, where he was being quizzed by the local media as to his chances of a back-to-back victory repeat in Monaco next weekend.

“I think it’s going to be a great opportunity for us to be strong again,” he said.

Sebastian Vettel has defended his former mentor Michael Schumacher.

The seven time world champion has been roundly criticised since last Sunday’s Spanish grand prix, after crashing into Williams’ Bruno Senna at the end of the Barcelona straight.

He called the Brazilian driver an “idiot” on the radio and later defended the outburst, but the FIA did not agree, imposing a five-place qualifying penalty for Monte Carlo for causing a collision.

“For us, that manoeuvre of Michael’s cost us a lot,” Red Bull team principal Christian Horner said on Austrian Servus TV.

He said the debris from the crash not only damaged Vettel’s front wing, but led to the reigning world champion having to serve a drive-through penalty due to activating his DRS wing in the yellow-flag zone.

German Vettel, however, defended Schumacher.

“In those situations we don’t have much time of course,” he said, “and you can get very great speed differences (between the cars) on the straights.

“I think it should be classified simply in the category of racing accidents. Unfortunately it happens,” said the reigning world champion.

“Of course you can always say what is what afterwards,” added Vettel, “just as you can say that it always takes two to tango.”

Mercedes’ Norbert Haug was less eager to comment, although he did tell Germany’s Sport1 that the team “accepts the verdict of the race stewards”.

Pirelli stands ready to supply special ‘qualifying tyres’ to formula one teams next year.

With the emphasis of the sport’s spectacle now relying on the complex and heavily degrading control tyres, it was the qualifying session that suffered last weekend in Barcelona.

Arguably to the detriment of Saturday’s spectacle, teams took an exceedingly strategic view of the fight for pole position, with some drivers sitting out the decisive ‘Q3′ runout altogether.

One solution, according to Pirelli’s chairman Marco Tronchetti Provera, is the return of ‘qualifying tyres’.

The proposal has been made following recent criticism, notably by seven time world champion Michael Schumacher, of Pirelli’s 2012 product.

Tronchetti defended his marque’s approach.

“What we have is many competitive cars, which is what the teams wanted — opprtunity for everyone who is able to win,” he told Italian radio Rai GR Parlamento.

“So it’s fine if someone complains. We are available to the teams. We are ready to make qualifying tyres tomorrow.

“But they are choices that are not ours.”

Martin Whitmarsh is sure McLaren’s recent errors will not affect contract negotiations with Lewis Hamilton.

The British team’s latest mistake not only cost Lewis Hamilton pole in Spain, it put the 2008 world champion to the very back of the grid.

Asked if he worries that the now seemingly constant flow of team gaffes will damage McLaren’s efforts to re-sign Hamilton, Whitmarsh insisted: “No, I don’t.

“He has got to build the support of the team, he has got to feel comfortable doing it, he has got to want to drive and he is in good shape,” British newspapers quote the McLaren team principal as saying.

“I look forward to working with him for a long time to come.”

But Whitmarsh admitted that, given Hamilton’s tumultuous 2011 season, he was worried the British driver might have despaired last Saturday when the team’s refuelling mistake cost the 27-year-old pole.

“I was concerned,” he said, “because it is a pretty tough thing to happen to a driver.

“But I have to say he showed some greatness I had not seen before. By the end of our chat he was consoling me.

“The relationship between Lewis and the team is stronger and better and hopefully we will work together for a long time,” added Whitmarsh.

Even amid the chaos of the 2012 pecking order, the star performer is obvious.

That is the view of former F1 driver Christian Klien, who confirmed to the Austrian news agency APA that one of his current roles is a simulator driver for the sport’s latest winning team, Williams.

“It (2012) is very open,” he said, “but for me Fernando Alonso stands out.”

Equal with Sebastian Vettel, Spaniard Alonso is at the top of the drivers’ world championship, a full eight points clear of Lewis Hamilton.

The Spaniard’s car has been the struggling Ferrari F2012, but he has never finished a race this season lower than ninth (China).

He has therefore scored points at every opportunity, even finishing first and second in Malaysia and Spain respectively.

“Alonso has an inferior car,” Klien explained, “but he uses every single little opportunity.

“He is the most complete driver who gets the most out of the package he has.”

Triple world champion Sir Jackie Stewart agrees that, among arguably the most competitive grid of drivers since the late 80s, Alonso is the standout performer.

“Right now we have the best generation of drivers we’ve had for a while,” the famous Scot told the Spanish sports daily AS.

“Everyone talks about Vettel, who is a great driver, and also Hamilton of course, but there is also Button, Schumacher, Kimi — all champions.

“There are others like Webber who also have the quality to win, young drivers coming up, many of them are very good, but also it is true that Alonso is fantastic.”

Asked why the Spaniard has not added a title to his tally since 2006, Stewart said: “The explanation is easy — he hasn’t had the luck to get the best car.

“Now he has one that isn’t good, but it’s in those circumstances that you see even more the quality that he has,” said Stewart.

Given Alonso’s push to the top of the championship with a sub-standard car, therefore, all the talk about Ferrari writing off the 2012 championship has been silenced for now.

“We have to keep developing the car,” Stefano Domenicali, Ferrari’s team boss, said after Barcelona, where significant upgrades were brought to the F2012 package.

“We are not yet fast enough to consistently fight for the podium, but that is the only option if we want to be in contention for the title,” he insisted.

Five races in, F1′s cleverest brains are still yet to decode the mystery of the bizarre and fascinating 2012 season.

As was the case when he utterly dominated last year, Sebastian Vettel is still leading the drivers’ points chase.

But, before last weekend, if he had been told that Williams’ Pastor Maldonado would be the winner of the Spanish grand prix, the German admitted: “Well, I would have put a lot of money on them!

“I think the odds weren’t bad,” he smiled.

Indeed, the major British bookmaker William Hill was taking bets at 500-1 prior to the Barcelona weekend.

A spokesman confirmed that only two bets at 10 pounds or above were placed on Maldonado prior to qualifying.

“I’m sure Williams don’t understand why they just won the race here,” McLaren’s Jenson Button is quoted by the Guardian newspaper.

But the previously-derided ‘pay driver’ Maldonado is not the only potential new winner in 2012, after Jenson Button, Fernando Alonso, Nico Rosberg and Vettel won the opening four grands prix.

A detailed look at F1′s specialist reporting in the past few weeks shows that Lewis Hamilton, Mark Webber, Kimi Raikkonen, Romain Grosjean, Michael Schumacher, Sergio Perez and Kamui Kobayashi are all also widely regarded as genuine victory candidates in 2012.

And given that their teammates have won grands prix this season, even the struggling Felipe Massa and Bruno Senna should be added to that list.

“Dammit, let’s go for (HRT’s) Karthikeyan!” wrote Chris Hockley in the Sun newspaper.

“It’s really quite crazy right now,” Vettel, who despite his young age would count himself among F1′s currently perplexed purists, told Germany’s Auto Motor und Sport.

“What’s happening is difficult for us to explain,” he added.

The situation has split the F1 audience, with the purists shaking their heads, and others marvelling at the unprecedented spectacle.

“The spectacle has taken over the sport,” said the Paris daily Le Figaro.

“Even the teams can’t be sure who will be the hare and who will be the tortoise at any given track,” wrote Hockley.

Alonso, who is the joint championship leader, is in the purists’ camp.

“Of course it is attractive for the spectators that we are going to Monaco not knowing if we will fight for victory or be left out of the points,” he is quoted by El Pais.

“But in a way, after eleven years in formula one and now I’m at Ferrari, I would like to have more stability,” the Spaniard admitted.

Sir Jackie Stewart said: “What’s going on is unbelievable, which I think is the outcome of the new rules, new tyres — I think it’s many factors,” he told the Spanish sports daily AS.

“What’s happening,” said Maldonado’s race engineer Xevi Pujolar, “is that these tyres are allowing teams who do not have the biggest budgets to be eligible for really good results.

“The reason is that the most important thing now is to have a good setup and also some luck with the temperature.”

Pirelli, F1′s tyre maker, has received both criticism and praise for its huge role.

“Pirelli have been both bold and brave,” Sun journalist Hockley said. “It can’t be easy for a manufacturer to make tyres that sometimes wear out faster than you can say Mercedes.”

Marco Tronchetti Provera, the Italian marque’s company chief, is unapologetic.

“What we have provided is what the teams have asked for, and it was not easy,” Italian language reports quote him saying. “Our engineers have done an extraordinary thing.”

F1′s astonishing season continues to live up to the hype, as a fifth driver and constructor on Sunday won the fifth grand prix of 2012.

Not only is the victory Pastor Maldonado’s first, his walk up the steps at the Circuit de Catalunya was the first taste of the podium in his two-season F1 career.

It’s also the first Venezuelan triumph in the sport’s history, and a hugely popular victory for Williams, the once-great British team headed by Sir Frank Williams, whose 70th birthday was warmly celebrated in the paddock on Saturday.

“Boy did we need that,” said Williams on BBC television.

And asked how he feels on Sky television, he smiled: “Relief.”

“Some said Maldonado was a pay driver and he didn’t deserve his place in formula one but they’ll be eating their words now,” commented former team driver David Coulthard.

“That was a fantastic drive,” added Coulthard, referring to Williams’ first win since Juan Pablo Montoya in 2004.

Williams enthused: “I didn’t see him (Maldonado) make one single mistake.”

“You can’t really fault him,” agreed Williams’ 1996 world champion Damon Hill.

Amazingly, however, away from the champagne, Sebastian Vettel’s sixth place leaves him at the top of the drivers’ championship, and he is now neck-and-neck with Fernando Alonso, who finished second on Sunday in the improving Ferrari.

Lewis Hamilton, who finished dead last on Sunday and finished eighth, is third in the points classification, ahead of Lotus’ Kimi Raikkonen.

Finn Raikkonen finished third on Sunday, and is the favourite to become F1′s sixth different winner of 2012 in Monaco in a fortnight.

“We showed we still have the speed,” the Lotus driver said after the Spanish grand prix. “If we had a few more laps, we could have fought for a victory.”

The penalty might be harsh, but the loss of Lewis Hamilton’s pole in Spain is just the latest calamitous mistake by McLaren.

That was the tone of the paddock’s reaction to the news late on Saturday that a McLaren gaffe saw the FIA send Hamilton from first to last on the Spanish grand prix grid.

The Sun newspaper called it a draconian “24-place grid penalty” imposed by the FIA after an “astonishing cock-up” by McLaren.

Hamilton was told on the radio to pull over after his pole lap due to a “technical problem”.

Sporting director Sam Michael argued ‘force majeure’, but the stewards ruled that it had been entirely McLaren’s fault that not enough fuel was put into Hamilton’s car to ensure a scrutineering fuel sample.

Writing in the Telegraph, Tom Cary said the severity of the disqualification “raised eyebrows”, but agreed that “McLaren’s mistake was horrendous”.

He said it has been “a season of errors” by the famous British team, who are yet to get Hamilton’s signature on a new contract beyond 2012.

“Hamilton must be seething,” read an article in the Daily Mail newspaper, while The Times laid out McLaren’s “catalogue of errors”.

27-year-old Hamilton’s “raw talent is being thwarted by mishap and cock-up,” said journalist Kevin Eason.

“McLaren are lovely people but how the hell do they get themselves in this position?” wrote the Mirror’s Byron Young on Twitter.

Even the non-English language media agreed.

“It was another great mistake by McLaren that could eventually cost Hamilton the championship,” wrote Livio Oricchio in O Estado de S.Paulo.

Italy’s La Stampa called McLaren’s fuel gaffe a case of “harakiri”.

Germany’s Auto Motor und Sport added: “It was error number 13 for McLaren since last year”.

While highly critical of McLaren’s own-goal, however, the feeling in the paddock is that the stewards’ penalty – although accepted by McLaren – was overly harsh.

“Back of the grid? Way, way too harsh”, said the Mirror’s Young on Twitter.

“Draconian penalty in my view,” agreed PA Sport’s Ian Parkes. “Dropping Q3 time would have sufficed.”

Sky commentator Martin Brundle added: “(I) feel they should have deleted that (Q3) laptime only which would have put him sixth”.

And excluding Hamilton from Q3 altogether would have put him 11th. Now, he will be “lucky to score a point”, Auto Motor und Sport predicted.

In the Independent, however, David Tremayne noted: “Welcome to the draconian world of F1.”

David Croft, the lead Sky commentator, said the FIA stewards had acted correctly.

“A good rule should be one that covers all eventualities with a penalty that acts as a deterrent which in this case is what happened.

“Too little fuel can’t be tolerated,” he added. “It seems harsh but had Lewis taken pole by one thousandth of a second, would it be harsh then?”

The Spanish fans – not Hamilton’s biggest supporters dating back to his spats with Fernando Alonso in 2007 – were happy.

Asked on the El Mundo website whether the penalty was fair, 76 per cent answered yes.
