Paul di Resta has hinted he would leap at the chance to replace Michael Schumacher at Mercedes.

The German marque’s Brackley based chief executive Nick Fry this week earmarked impressive Force India driver di Resta, earlier a Mercedes protege, as an ideal successor should Schumacher not stay beyond his 2012 contract.

Asked about Fry’s comments and the media speculation on Wednesday, di Resta said in Monaco: “It’s always nice to have the press interest and people looking out for you, but I need to stay focused on doing the best job I possibly can.”

He told Sky Sports News: “It’s no secret that I want to be a race winner and world champion — and to do that, I need to be in a great car.”

Sergio Perez admitted to mixed feelings on Wednesday as he returned to Monaco.

The last time he was in the Principality to race – for his debut grand prix in the fabled Principality – he was hauled away in an ambulance, having been knocked unconscious in a huge qualifying crash.

“To me it’s unbelievable to be back here after such an accident,” the 22-year-old said on Wednesday, according to Germany’s Auto Motor und Sport.

Mexican Perez said Monaco is still his favourite track.

“It is definitely not a good feeling that the walls are so close, but we know the risks. It’s a special place.

“I can remember everything right up to the crash. The next thing I know was that I was on the way to hospital — I was unconscious for several minutes.

“After such an accident it is not easy to come back — I cannot say for sure how I will feel when I come out of the tunnel for the first time. But I think it will be completely out of my head.”

Perez said he really needed “four or five” races to recover from the heavy concussion, but that there was pressure from sponsors to come back as soon as possible.

“I wanted to get back into the car in Montreal, but it was impossible,” he recalled.

“In Valencia it was very difficult for me.”

Now, he is hoping for a very different Monaco weekend, after looking strong last year until his crash.

“Our goal must be the podium. I hope to find a good setup although we have recently had a little problem with the traction.

“We are so close to the top that every tenth can make a difference.

“After our second place in Malaysia, maybe the next step will be victory — I don’t know if we will succeed. But the opportunities are there,” said Perez.

Ross Brawn revealed on Wednesday he missed the recent Spanish grand prix to have checks on his heart.

After handing over to his Mercedes deputy Nick Fry in Barcelona, fellow Briton Brawn is back in action as the team boss in Monte Carlo.

Rumours hinted there was more to the story, but Brawn insisted to a German newspaper earlier on Wednesday that he was simply advised by doctors to take the weekend off after a night in hospital for checks.

He then told reporters in Monaco his symptoms had been “arrhythmia”, or an irregular heartbeat, insisting he is “back to normal now”.

Brawn, 57, joked the heart problem was triggered by watching an exciting football game on television.

It is believed static electricity could have sparked Williams’ garage fire two weeks ago in Barcelona.

Even in the Monte Carlo paddock, the huge Spanish blaze was still a hot topic.

The British team and the FIA conducted investigations, but there has been no definite finding about the cause of the fire.

Germany’s Auto Motor und Sport reported suggestions simple static electricity, caused by the specific weather conditions and the fact a container was not grounded at the time, was the culprit.

Williams has scrambled to be ready for Monaco, but the only obvious sign of the fire on Wednesday was one missing mechanic, who is still recovering from burns.

“He’s on the road to recovery,” said co-owner Toto Wolff.

It is believed the mechanic was pumping fuel from one container to another when the fire started.

Wolff confirmed the static electricity theory.

“This is extremely rare. The weather may have played a role, as we had low pressure over Barcelona that day,” he explained.

Auto Motor und Sport said Williams lost mainly computers in the fire, but the crucial data survived. Of the team’s 150 radios, only 40 were intact.

Wolff said Bruno Senna’s chassis survived because of the partitions at the back of the main pit area.

“They are flame retardant,” he confirmed. “This meant the fire did not come beyond the back (area). The walls melted in the heat, but they didn’t burn.”

And financially, the Oxfordshire based team is completely undamaged, due to insurance.

A favourite for victory this weekend, Pastor Maldonado is reportedly lucky to be gearing up to race in the Principality at all.

Bild newspaper recalls that the Venezuelan, who defied his ‘pay driver’ critics by winning for Williams in Spain two weeks ago, was actually banned after an horror incident on the streets of Monte Carlo seven years ago.

Racing in the Renault World Series in 2005, the then 25-year-old ignored yellow flags before striking and severely injuring a marshal.

Organisers of the Monaco grand prix reacted by banning Maldonado from the street circuit for life.

Germany’s Bild revealed that Maldonado’s wealthy father intervened, promising to pay for the marshal’s recovery and rehabilitation from a broken back.

That intervention saved Maldonado’s future formula one career, as no team would hire a regular driver that cannot participate in the sport’s most famous race.

Maldonado is therefore a favourite for victory this weekend, with his Williams now acknowledged as arguably the best in the entire field when it comes to slow-speed traction.

And in his four seasons of GP2 between 2007 and 2010, Maldonado finished on the podium each time, winning and achieving pole position twice. In 2006, he won in Formula Renault.

Last year, in qualifying for his first Monaco grand prix, he qualified his then struggling Williams in eighth place, comfortably ahead of Rubens Barrichello.

“He is very good at Monaco,” agreed Barrichello.

In the 2011 race, Maldonado was fighting for fifth when he crashed with Lewis Hamilton.

“If the last sector in Barcelona is the marker, then the Williams will be unbeatable in Monte Carlo,” Germany’s Auto Motor und Sport quotes Dr Helmut Marko as saying.

The breakthrough success in Barcelona has piqued the interest of Maldonado’s native Venezuela, having not had an F1 points scorer since the ignominious Johnny Cecotto in 1983.

“My country will be following every second of the next race,” Maldonado is quoted by O Estado de S.Paulo newspaper.

“I love street circuits, this one in particular. My style of driving fits perfectly with Monaco. I am ready to get another great result.”

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.”

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.”

It is possible formula one teams will be limited to a budget cap in 2013, according to Germany’s Auto Motor und Sport.

The budget cap idea saw the sport almost implode amid the bitter political war of 2009, when proposed by controversial former FIA president Max Mosley.

But it is back on the agenda in 2012, and according to new rules – where a majority of teams can now push through a change – it could be imposed next season.

“Ten of the 12 teams are in favour,” Auto Motor und Sport said, referring to the push to have cost-cutting moved from the FOTA gentleman’s agreement to the actual sporting regulations.

It means that the two dissenting teams, the Red Bull-owned Red Bull Racing and Toro Rosso, will have no say.

“The cost to be competitive in formula one at present is too high,” the boss of the energy drink company’s premier team, Christian Horner, said recently. “I don’t think anybody will dispute that.

“The debate is how we achieve it.”

Not only that, the German report said nine teams are in favour of Mosley’s old budget cap idea, with annual expenditure limited initially to EUR 170 million and then diminishing to 100 million over a few seasons.

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.

Charlie Whiting has defended the decision in Spain to move Lewis Hamilton from pole to the very rear of the grid.

Although McLaren was widely criticised for making a grave error, the stewards’ penalty was at the same time described by the world’s press as “draconian”.

“Quite frankly I did not expect the penalty that we received,” said McLaren team boss Martin Whitmarsh.

Indeed, given that McLaren’s fuel indiscretion occurred only in the decisive Q3, why not simply delete Hamilton’s Q3 laptimes, thereby putting the Briton mid-grid for the race?

“We had no room to move,” Whiting, the FIA’s race director, responded to Germany’s Auto Motor und Sport when told that Hamilton’s penalty seemed too severe.

“If there is a violation, it applies to the whole session, not just part of it,” he insisted. “Qualifying begins with Q1.”

Whiting explained that if Hamilton had only lost his Q3 time, a precedent would have been set tempting teams to risk not being checked for the mandatory 1 litre fuel sample in post-qualifying scrutineering.

Auto Motor und Sport said only one or two fuel samples are actually checked after qualifying at grands prix.

Competitors could, therefore, genuinely “run the risk” of using less fuel than is allowed in Q3, if the penalty for being caught is relatively light, Whiting argued.

He recalled last year’s German grand prix, when Sebastien Buemi was sent to the back of the grid because his fuel sample showed irregularities.

As it was not possible to check if the illegal fuel had also been used in Q1 and Q2, the Toro Rosso driver had to be disqualified from qualifying, Whiting argued.

Jerome d’Ambrosio is the latest name linked with struggling Felipe Massa’s Ferrari race seat.

While Mark Webber or Sergio Perez are the Maranello team’s more likely longer term solutions, Ferrari may be looking simply for a stop-gap solution, having reportedly run out of patience for Brazilian Massa’s lack of pace and results.

The French sports daily L’Equipe named d’Ambrosio, the Belgian driver who lost his Virgin/Marussia seat at the end of last season.

He is managed by Eric Boullier, and now Lotus’ reserve driver.

Also named as potential substitutes for Massa in recent days were Nico Hulkenberg, Paul di Resta and Kamui Kobayashi.

But, according to L’Equipe, d’Ambrosio “has the advantage of being immediately available, giving Ferrari time to find a more permanent solution” for 2013.

Also ready to step in now is Adrian Sutil, the former Force India driver who is putting his career back together after the Eric Lux assault affair.

“I have no money to offer,” the German is quoted as saying. “After five seasons, people know what is my level. I want a normal salary, that’s all.”

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”.

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.”

Two days after winning in Spain, Williams is scrambling to put together the equipment it needs to contest next weekend’s Monaco grand prix.

Mere hours after Pastor Maldonado secured the once-great British team’s first victory since 2004, a huge fire broke out in the pits, leaving one team member still in a Barcelona hospital with burns.

“His family are in constant communication and he is in good spirits,” Williams said in a media statement.

The Oxfordshire based team is now making efforts to ensure it can race in Monte Carlo, having lost a lot of equipment in the fire.

Mercifully, however, Bruno Senna’s car appears to have survived, with the Finnish broadcaster MTV3 saying an initial inspection of the chassis showed no devastating damage.

Maldonado’s winning car was in parc ferme at the time of the incident.

“We had a lot of damage and lost a lot of equipment, including IT equipment,” chief operations engineer Mark Gillan said, according to the Daily Mail.

“Over the next couple of days we will be looking at where we are parts-wise.

“We will have everything we need to run operationally at Monaco, but we may be missing a few of the extras because obviously we don’t carry a complete set of spares for everything,” he said.

It is believed more than one rival team has offered to help Williams by loaning the Sir Frank Williams-led outfit any equipment it needs.

A McLaren spokesman confirmed the Woking based team has offered to help.

Germany’s Bild newspaper said Williams’ damage bill runs into the millions.

Team manager Dickie Stanford denied a rumour the fire was caused by a cigarette in the vicinity of Senna’s fuel tank while it was being emptied.

“We don’t know the cause, but we would never allow smoking in the pits,” he insisted.

Williams and F1′s governing FIA are investigating.
