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.

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.”

Former F1 driver Mika Salo believes his Finnish countryman Valtteri Bottas is being groomed by Williams for a race seat — in 2012.

When the Toto Wolff-managed Bottas, 22, was announced as the British team’s 2012 reserve, Sir Frank Williams said he would practice on 15 Friday mornings and then “most likely” be replaced with a “more experienced driver” for the rest of those race weekends.

That more experienced driver would ultimately turn out to be Bruno Senna.

So with Brazilian Senna struggling so far in 2012, Salo has revealed he senses things could be about to change.

“Bottas is incredibly respected by the team,” Salo, now a commentator for the Finnish broadcaster MTV3, said.

“When I spoke with Frank Williams, he praised Valtteri to the skies, and said that he belongs in the races.

“I asked him when and he said it wouldn’t be long.

“Yes, I read between the lines that he means this season,” added Salo.

One major spanner in the works, however, is that Senna brings crucial sponsorship to Williams.

“It is a difficult situation for Williams, where both drivers bring money,” Salo acknowledged.

“But the good thing is that Frank Williams is not a businessman first, he is an old racing driver. He thinks about nothing else but how to make his team successful.

“Although Senna is a nice guy, he is not able to drive at the level that he needs to be at.”

When asked about Salo’s theory, Bottas commented: “I have no information.”

Narain Karthikeyan has played down reports he could lose his seat at HRT because of a lack of sponsorship.

An Indian newspaper this week said the 35-year-old is a million euros short of guaranteeing his place at the struggling Spanish team through November’s Brazil finale.

“Right now, everything is as it should be,” he is quoted by France’s autohebdo.fr.

“Early in the season, (team boss) Luis (Perez Sala) said that if I was not close enough to my teammate, there is a chance I will not finish the season.

“That was put into my contract, but for now I respect all the conditions. There is no reason that I will not be driving (the rest of) this season,” added Karthikeyan.

He admits, however, to some frustration about HRT’s continuing rear-of-the-field position.

“To be honest I wasn’t expecting the start of 2012 to be on the same lines as last year,” the Indian driver told the Hindustan Times newspaper.

“Yes I expected teething problems but not to this extent.”

He also admits he expected the team to test at Mugello last week.

“Personally speaking, I would’ve preferred some seat time at Mugello since I didn’t get any pre-season testing compared to my teammate who did the Jerez test with the old car,” said Karthikeyan.

“I was originally told that we would do the Mugello test but we decided to focus on putting the car together instead.”

Narain Karthikeyan is not guaranteed his HRT seat for the whole of the 2012 season.

Following what the reporter referred to as a ‘chat’ with the Indian driver, the Times of India claimed Karthikeyan is “a million euros” short of a contract that will see him definitely race through November’s Brazil finale.

The 35-year-old also began the 2011 season for the struggling Spanish team, but was replaced by the Red Bull-funded Daniel Ricciardo mid-season.

The Times of India said securing the extra million in sponsorship is proving “difficult” for Karthikeyan.

“Sponsors are happy to give him money but not to the team, as obviously they do not want to be associated with a struggling outfit,” the report said.

The good news for Karthikeyan, according to the journalist Harish Samtani, is that his sponsorship deal with Tata brings to HRT the Williams gearbox, valued at about EUR 5 million.

The report said the link between Karthikeyan and Williams is the British team’s joint venture with Jaguar, which is owned by the driver’s sponsor Tata.

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.

The Spanish windscreen repair and replacement company and HRT Formula 1 Team have signed a collaboration deal for Cristalbox to become a new sponsor of the Spanish outfit for 2012. Cristalbox, who have already been linked with the motorsport world for a few years, have decided to extend this link and have taken a step into Formula 1 alongside HRT Formula 1 Team, with the objective of supporting the Spanish team’s project in the pinnacle of world motorsport.

The deal with which Cristalbox joins the team as a sponsor has a one year duration and the glass repair company has bolstered its commitment to HRT’s project by completing a spectacular glazing job at the new Caja Mágica headquarters in Madrid. The creation of a curtain wall at the team’s workshop supposed the installation of more than 25,000 kilogrammes of specially fabricated glass and will enable the team to make the most of the sunlight and environmental conditions.

Just like the conditioning of the other project areas at the Caja Mágica facilities, the installation and reinforcement of the curtain wall has been completed in under a month, thus proving the capacity of the Spanish company to expand its services.

Javier Celaya, Cristalbox General Manager: “A passion for cars is in the genes, the DNA, of our brand and top level competition reflects the essence of Cristalbox’s values: precision, speed, safety, resistance, reliability…From an advertising point of view, after two years sponsoring Formula 1 broadcasts, this was the logical evolution: to form a part of the competition. With HRT we can support a credible Spanish project in the pinnacle of motorsport and strengthen the reach of our brand to our targets”.

Luis Pérez-Sala, HRT Team Principal: “Formula 1 is all about technology and speed, two basic principles which we share with Cristalbox. They are a leading company in our country and we’re proud that they decided to fully submerge in Formula 1 alongside us and fully back our project. I want to thank them for the trust they have put in us and also for the extraordinary efficiency with which they have completed the structure and glazing of the workshop area in our new headquarters at the Caja Mágica. It was a structural and temporal task and they passed it with flying colours. We hope to overcome many other tasks alongside them this year”.

Carlos Sainz jr is on course for a future in formula one.

The 17-year-old Spaniard is the son of Carlos Sainz, the former two-time world rally champion.

Sainz jr, however, has pursued a career in open wheelers, and – now that Daniel Ricciardo and Jean-Eric Vergne have stepped up – he is the new cream of energy drink Red Bull’s junior driver programme.

And another direct link to the world of formula one for Sainz jr is his new sponsorship deal with Cepsa, the Spanish oil company that is also Red Bull-owned Toro Rosso’s main backer.

Sainz jr’s new Cepsa deal is for his participation this year in the British and Euroseries F3 categories, but “Our intention is to continue (beyond 2012),” Cepsa co-chairman Santiago Bergareche is quoted by Marca newspaper.

“Hopefully everything goes well and Carlos will be in that world (F1) one day,” added Cepsa chairman Alfonso Escamez.

He said the deal does not guarantee Sainz jr a future in f1.

“The sponsors have no say on the teams of the drivers. We can try to influence, to give our opinion, but we are not (able to decide) on that side.

“We hope that it does happen, but it will not necessarily.”

Tony Fernandes has admitted he would have liked corporate Malaysia to have backed his formula one team.

The Malaysian entrepreneur founded a UK based start-up team in 2010, calling it Team Lotus before a bitter spat developed with the Lotus name’s owner Proton.

“While I was building a formula one team, I was being sued by my own countrymen,” he told The Star newspaper.

“We’re the only true formula one team developed in Malaysia.”

Now called Caterham, the team’s only Malaysian sponsorship is from AirAsia — Fernandes’ own low-cost airline.

“Never mind that we were not sponsored (by Malaysia), that’s a company’s prerogative,” he said. “But, we were sued.”

Some have accused Caterham of not having progressed much since 2010, but Fernandes strongly disagrees.

“Two years ago we had nothing. We’re now 1.5 seconds away from Red Bull who are the world champions. We’re closing the gap.

“You can’t build Rome in a day,” he insisted.

Lucas di Grassi has admitted that even his continuing role at Pirelli is not a ticket back onto the F1 grid.

“I’m in the best possible position technically, as the driver with knowledge of the tyres – almost choosing them for next season – it puts me in a very comfortable position.

“Of course I want to race again with a team and I’m working on it,” said the 2010 Virgin driver, who was replaced by the now Marussia team with Jerome d’Ambrosio at the end of his only season in F1.

“The only problem is the lack of sponsorship,” di Grassi is quoted by Globo. “Let’s hope some Brazilian companies want to come in to support.”

Martin Brundle, a former F1 veteran whose son Alex now competes in the lower-tier GP3 series, admitted sponsorship is a problem for aspiring racers.

“Drivers are paying as much as $10 million to be a reserve at some teams,” the British commentator told the Daily Mail.

“Nine men who raced in F1 last year don’t have a drive any more. As soon as the money runs out, they’re replaced by someone who does have money.”

Rumours that a top English premier league football club is entering formula one as a sponsor have proved correct.

Ever since Sauber has been running teaser ‘Out of the blue’ and ‘True blue’ graphics on its engine cover livery in China and Bahrain, speculation about the identity of the forthcoming sponsor have been swirling in the F1 paddock.

We reported the rumour that the deal could be with the Russian billionaire Roman Abramovich, to promote his football club Chelsea.

Swiss F1 team Sauber confirmed the “new and innovative partnership” on Monday.

“The C31 sporting the blue logo of Chelsea FC will be seen for the first time at the Spanish grand prix,” the Hinwil based team announced in a media statement.

“A partnership like this between formula one and football has never existed before in this form, yet there are numerous commonalities and possible synergies,” said Sauber chief executive Monisha Kaltenborn.

The statement said Chelsea will in turn display Sauber’s logo on its advertising boards and interview walls, ensuring one another “a significant market presence outside their original sport”.

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.”

HRT has announced it will sit out next week’s rare in-season formula one test at Mugello.

For the first time in years, the sport has relaxed slightly its strict testing ban in order to give teams the chance to run between grands prix.

The three-day session at Ferrari’s Italian circuit will begin next Tuesday, during the three-week gap between Bahrain and Spain.

Struggling backmarkers HRT, however, will not be there, opting instead to be “completely focused” on relocating to its new Caja Magica headquarters in Madrid.

Every other team will be at Mugello, 30 kilometres from Florence — the first in-season test for four years.

26 drivers will be in action, as will a lot of update packages following F1′s return from the hectic ‘flyaway’ season.

Red Bull, Ferrari, Mercedes, Sauber, Marussia and Toro Rosso will use their regular race drivers.

Running regular racers and a tester will be Lotus (Jerome d’Ambrosio), Williams (Valtteri Bottas) and Force India (Jules Bianchi).

Germany’s Auto Motor und Sport said Caterham is “using the opportunity to earn some money” by accepting the sponsorship of the Venezuelan Rodolfo Gonzalez.

McLaren has scheduled to run its testers Oliver Turvey and Gary Paffett, although Lewis Hamilton has indicated he might gatecrash the programme in order to help solve the MP4-27′s newfound tyre problems.

With the F1 world now returned from Bahrain, the sport is assessing the fallout of one of the most controversial grands prix in history.

The drivers were conspicuously quiet over the saga in the island Kingdom, but – with no contract tying him down – former Force India driver Adrian Sutil admitted he was glad he was not there.

“In a situation like that, it is probably better not to go,” the German said on Sky Deutschland.

“On the one hand, the decision was made (to go to Bahrain), on the other hand, it’s very difficult when there are so many problems in a country.”

Red Bull reserve driver Sebastien Buemi, who has family living in Bahrain, does not agree at all.

“I arrived on Monday and I had no problem — maybe there were a few more police than two years ago, but nothing happened to me,” the Swiss insisted on Austrian Servus TV.

Force India and Sauber, however, witnessed Molotov cocktail attacks on their treks to and from the circuit.

And Caterham team spokesman Tom Webb told the Sun that there was “one minor incident when one of our (hire) vans slowed down in traffic and its occupants saw a local youth on the side of the main road brandishing a bottle with a rag stuffed in its neck”.

World champion and race winner Sebastian Vettel also admitted the feeling was tense in the paddock throughout the weekend.

“It was not easy for anyone,” the Red Bull driver admitted, according to SID news agency, “but I’m glad that nothing happened to any of us (in F1).”

And the Telegraph quotes Vettel adding: “Hopefully, we come back in the future when everything’s a little bit safer.”

Reuters reports that Vodafone, the main sponsor of the half Bahrain-owned McLaren team, sent no staff to the country and expressed concerns to the British outfit.

But Jim Wright, an F1 sponsorship expert, told the Guardian that he thinks while the sport’s image took a beating last weekend, sponsors will be happy.

“Most teams handled a difficult decision very well,” he said. “On that basis I think a lot of people would be pleased with that and happy to get involved with them.”

The television audience was also unaffected – even boosted – with the BBC reporting more viewers for Bahrain than Australia and Malaysia, and Germany revealing similarly strong figures.

Still, there remains criticism.

“Now is an opportunity to reflect,” former F1 driver Alex Zanardi told Tuttosport, “and make sure that major sporting events are assigned only to governments that deserve the honour of hosting them.

“Ecclestone is brilliant and has made formula one what it is, but he can’t administer races at any cost and above all else,” insisted the Italian.

Due to security fears, Force India sat out a practice session on Friday so that staff could return to their hotels in daylight.

F1 chief executive Bernie Ecclestone was reportedly enraged, and according to rumours got his revenge by instructing Formula One Management’s television cameras to ignore the Silverstone based team’s cars in qualifying.

“There was a bit of fuss about what we did,” deputy team principal Bob Fernley is quoted by Spain’s AS newspaper, “and it was not easy, but I think it turned out to be the right response.

“We had a lot of pressure, our attitude was not well received,” he confirmed, “but I think that we had a duty of care to our employees, and to do the right thing by the team.”

Sauber’s ‘teaser’ has done the trick, triggering paddock speculation about its forthcoming major backer.

Last weekend in China, off the back of Sergio Perez’s recent push for victory at Sepang, the small Swiss team ran mysterious ‘Out of the blue’ signage on the C31′s engine cover.

The Blick newspaper said it was a “teaser” for a “big sponsor” that will be “announced in a few weeks”.

So who is it?

Germany’s Auto Motor und Sport relayed paddock rumours hinting that the deal could be with AT-T, the American multinational who last year pulled its title sponsorship of the then-struggling Williams team.

Another paddock whisper is that Sauber’s new deal could be with the Russian billionaire Roman Abramovich, to promote his English premier league club Chelsea.
