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.”

Heikki Kovalainen is looking for Caterham to move into the midfield, according to his new management company.

Having handled his own career in the wake of Flavio Briatore’s demise, Finn Kovalainen recently signed up with IMG, the sports and entertainment management giant.

The 30-year-old has rebuilt his reputation since 2010 in the wake of mixed tenures for top teams Renault and McLaren.

According to IMG Motorsport’s head of clients Martin Anayi, Kovalainen is now regarded by formula one team bosses up and down pitlane as among the top best drivers.

“He is a great guy,” Anayi is quoted by Finland’s Turun Sanomat newspaper.

“Heikki’s potential is obvious and he definitely wants to succeed.”

There have been rumblings in the paddock that Kovalainen is disappointed that, despite being consistently the best of F1′s new teams since 2010, Caterham is yet to break into the midfield.

“This is only the team’s third season, so there are still some growing paints,” IMG’s Anayi acknowledged.

“Heikki has a strong desire to compete, and not just with his teammate Vitaly Petrov. The team’s boss Tony Fernandes wants to get in with the middle group.

“This means that the team needs to regularly get into the Q2 stage of qualifying and in the race be aiming for the points,” he insisted.

Formula one is worth about $8 or $9 billion, as the sport’s owner CVC confirmed it has this week sold a 21 per cent stake to new investors.

News of the sale coincided with the launch of pre-marketing ahead of one of the biggest ever sports floatations, data by the financial experts Thomson Reuters shows.

“It’s cheap compared to Facebook,” chief executive Bernie Ecclestone told reporters on Tuesday, confirming that the Singapore IPO looks set to go ahead soon “with no dramas”.

“All the things that have to happen have happened. It will be finished by the end of June,” the 81-year-old is quoted by the Telegraph.

F1′s new one-fifth owners are US managers Waddell and Reed, the powerful Blackrock and Norway’s central bank Norges.

“It’s a great way to start the IPO and lets investors know what they can expect,” said Ecclestone.

The diminutive Briton said he is keeping his 5.3 per cent stake, and staying in charge. His former wife Slavica controls another 8.5pc, the news agency Bloomberg said.

“You might as well have asked Frank Sinatra who he would appoint to replace him,” Ecclestone insisted.

CVC said in a statement that is remains F1′s biggest and controlling shareholder.

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.”

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.”

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.”

Felipe Massa’s formula one career is on the brink of collapse.

Ferrari boss Stefano Domenicali left Barcelona insisting he expects the struggling Brazilian to “fight back starting in Monaco”.

“We absolutely need his points to also fight for the constructors’ title,” he said.

Earlier, the Maranello based team said on Twitter that Ferrari is “disappointed with” the 30-year-old’s performance.

When asked about that comment, a Ferrari spokesman told the Sunday Times: “It was a poor choice of grammar. We are disappointed in the outcome of Felipe but not with Felipe himself.”

But the very latest development is that Ferrari is now making it abundantly clear that Massa needs to up his game immediately.

In a statement posted on its official website, Ferrari said Massa’s teammate Fernando Alonso “has always maintained a very high level”.

As for Massa, his “drop off has made itself felt”, the report stated.

“The Brazilian had picked up 49 points two years ago and 24 the following year, while so far this season he has just 2,” said Ferrari.

“Everyone, he more than anyone, is expecting a change of gear starting right away with the Monaco grand prix”, the statement concluded.

Even Massa’s strongest supporters in Brazil, like the O Globo journalist Celso Itibere, admit the situation is dire.

“He is at risk,” said Itibere, “his decline is progressive, he is failing to react and he runs the real risk of not finishing the season.

“At this time Ferrari has no one to take the job. Everyone they would like to have there – Perez, Kobayashi, Webber – are not available.”

Tuesday’s edition of the Italian sports daily Corriere dello Sport will report that Massa’s ousting is imminent.

And the latest edition of La Gazzetta dello Sport did not even once mention Massa’s name. “It is as though he does not exist,” wrote the Brazilian journalist Livio Oricchio in O Estado de S.Paulo newspaper.

“Yet it is an Italian newspaper, and he is a Ferrari driver.”

When asked if he fears for his F1 career, Massa said in Barcelona last weekend: “No. I live in the present. What will happen will happen.”

Asked if he is afraid another bad performance will seal his fate, Massa insisted: “I’m not afraid of anything, especially criticism. It doesn’t affect me.”

Jaime Alguersuari has concluded he made “a mistake” to remain loyal to Red Bull late last season.

After testing Pirelli’s 2010 Renault car last week at Jerez, the Spaniard moved on to Barcelona to continue his work as a co-commentator for British radio.

However, he revealed recently that he might have been on the 2012 grid, had he not believed Red Bull executives who told him he would be at Toro Rosso this year.

“It was definitely a mistake not to negotiate with other teams,” said the Spaniard, “as I had the opportunity and declined offers,” he told Marca sports newspaper.

“I did that because I had loyalty to Red Bull.”

Asked if he has talked with anyone from Red Bull since his dismissal, the 22-year-old revealed: “The directors, no, the technical team, yes.”

It still pains him that, in explaining their decision, the Red Bull officials like Dr Helmut Marko insisted Alguersuari was not a potential winner.

“If you think that for six years they supported me then they changed their opinion overnight. One day you have a champion, the next you don’t,” he said.

Volkswagen, the German carmaking giant, has played down suggestions it could launch a formula one project some time soon.

“There are always rumours about Volkswagen and formula one,” said Jost Capito, who has taken over from Kris Nissen as the head of the Wolfsburg-based company’s motor racing boss.

However, he is quoted by Germany’s Sport1 as insisting that VW is only concentrating on its world rally programme.

“The WRC programme is approved from 2013 to 2015,” Capito insisted. “There is no room to think about anything else.

“It (F1) is not on our radar,” he is also quoted as saying by France’s L’Equipe. “Our hands are full already.”

In the wake of BMW, Honda and Toyota’s departures, the only mass production carmakers in F1 are Renault – as an engine supplier – and Mercedes.

Ferrari, McLaren, Lotus and Caterham produce niche sports cars.

Michael Schumacher has been pipped at the post in the race to be the world’s richest sportsman.

According to the Sunday Times’ annual listings, the seven time world champion’s (US) $823 million in career earnings is beaten only by golf legend Tiger Woods.

American Woods has earned $869 million in his own ultra-successful career, the newspaper found.

And the Sunday Times said the pair have each earned hundreds of millions of dollars more than other high-earning sportsmen, including Michael Jordan ($516m), Roger Federer ($316m) and David Beckham ($258m).

F1′s two other representatives, Fernando Alonso and Kimi Raikkonen, were way down the top-twenty list, with their respective earnings at about $161 million apiece.

McLaren’s world champions Lewis Hamilton ($89m) and Jenson Button ($85m), meanwhile, appear only on the list for British sportsmen, and they are both outpaced by the $129m earned by former Ferrari driver Eddie Irvine mainly through property investment.

However, Hamilton and Button have each earned more in their careers than David Coulthard, Nigel Mansell, former BAR boss David Richards (all $80m) and Sir Jackie Stewart ($67m).

Those earnings, however, are all dwarfed by Bernie Ecclestone’s estimated $4 billion, although the 81-year-old F1 chief executive does not appear at all on the list of the world’s richest overall.

That list is headed by mega-earners like Sauber sponsor Carlos Slim, who according to the Sunday Times is worth $71 billion.

Tuesday was a new experience for many F1 regulars; a rare in-season test on an unfamiliar track.

Some teams wanted the three-day session to take place at Barcelona, saving money ahead of the Spanish grand prix at the same venue, but Ferrari pushed hard – reportedly even waiving the circuit rental fees – for its circuit in Tuscany to get the nod.

The day did not start well weather-wise, but the spectators – reportedly 25,000, and visibly more than in Bahrain last weekend – came nonetheless.

“This is my first time here,” Sebastian Vettel, whose teammate Mark Webber kicked off proceedings for Red Bull on Tuesday, told Auto Motor und Sport.

Australian Webber, second fastest after the first morning behind crowd favourite Fernando Alonso, has been here before.

“I once did a sports car race here,” he said.

“It’s a bit too fast (for F1).”

Indeed, of the grand prix circuits, only Monza is faster. Nico Rosberg, in the Mercedes, gave Mugello a big thumbs up.

“1 to 10, I’d give it 8.5,” the German grinned.

It is an important test for Ferrari, but – contrary to earlier rumours – there is no ‘B’ car.

Alonso told La Gazzetta dello Sport that Mugello and then Barcelona next weekend will not make or break Ferrari’s championship.

“We need to catch up race after race,” said the Spaniard. “If we do poorly in Barcelona, it doesn’t mean our season is over.”

The French government is dashing to seal the lid on the country’s return to F1.

Bernie Ecclestone has said a deal has been reached to annually alternate a race between Paul Ricard in France and Belgium’s fabled Spa-Francorchamps.

But the final signature and official announcement are still missing.

David Douillet, the French sports minister, told Le Journal du Dimanche that the chance France will be on the 2013 calendar is “90 per cent”.

“The contract is going back and forth between the lawyers. I hope I get to London to meet with Bernie Ecclestone between Wednesday and Friday,” he added.

The newspaper said Douillet is dashing to complete the deal by this weekend’s presidential election, because socialist frontrunner Francois Hollande has hinted the grand prix project would be reviewed if he is elected.

Douillet admitted that it is “very likely” Hollande would “bury” the race.

Le JDD newspaper said organisers and Ecclestone have agreed the race sanctioning fee, EUR 22 million, which is still a few million short of guaranteeing a balanced budget.

And “without a balanced budget, we do not sign,” he warned. “The state, which does not participate financially, is still the guarantor of any debt.”

There also remains an odd silence from the Belgian side, who have not confirmed that Spa is the circuit that will alternate with France.

Rumours that F1 team owner Genii is contemplating buying the Group Lotus sports car company are continuing to gain steam.

That is despite Genii’s Gerard Lopez confirming recently that the Enstone based team has ended its sponsorship deal with the carmaker, even though the team will continue to carry the Lotus name.

But subsequent media reports indicate that the newly Malaysian conglomerate DRB-Hicom owned Group Lotus is for sale.

“Genii … is thought to be interested, and its boss, Gerard Lopez, is said to have had talks with Hicom, but also with (Group Lotus chief) Mr (Dany) Bahar about a possible management buyout,” read a report in the Independent newspaper.

Bahar is not ruling out the transaction.

“Whatever happens will happen,” he told the local Norfolk publication edp24.co.uk.

“Genii has expressed interest and if there is a good deal to be done, why should they not be interested? I think it would just make sense.”

James Key could be the next formula one engineer to join F1′s struggling giant Ferrari.

Multiple media sources, including the authoritative Italian specialist newspaper La Gazzetta dello Sport, say the Maranello based team is interested in Key, a 40-year-old Briton.

Key’s career dates back to the Jordan days, continuing through the transition to Force India, and he eventually joined Sauber in 2010.

He was the highly respected technical director at the Swiss team until earlier this year, and was therefore in charge of the impressive 2012 Sauber C31, amid speculation he had headed to Lotus’ sports car project.

But the media reports, including in the major German daily Bild, say Ferrari is now interested, particularly because Key is already familiar with the Italian marque through Sauber’s use of the Ferrari drivetrain.

However, when asked what truth there is to the Key rumours, Ferrari spokesman Luca Colajanni snapped: “Nothing, nada, niente!”
