Money could be at the heart of the delay in Lewis Hamilton’s re-signing with the McLaren team.

Until now, the British team has indicated it wants the 2008 world champion to stay on board, while 27-year-old Hamilton insists he has no plans to leave and will turn his attention to the 2013 contract soon.

But according to Blick newspaper, McLaren is pushing to cut Hamilton’s existing contract retainer “in half” to “about EUR 10 million”.

The Swiss report said the driver is unimpressed with the negotiations so far, but at least Hamilton’s mood has improved tenfold compared with his calamitous 2011.

It is a full year since Hamilton raged about his “frickin ridiculous” track rivals in the 2011 Monaco grand prix, when he also half-seriously suggested that the stewards were targeting him “because I’m black”.

He is back on top form this season, but still yet to win a race, arguably mainly due to McLaren’s numerous team mistakes.

Reports have suggested boss Martin Whitmarsh, who insists Hamilton “deserves” to win this weekend in Monaco, is worried the mistakes might drive the highly rated racer away.

On Wednesday, however, Hamilton denied he is frustrated.

“I’m not, no. This is the way racing goes sometimes,” he insisted.

“I could easily get frustrated because I could have a healthy lead in the championship — but that’s not the case.

“I don’t want to speak too early but something has definitely changed. Whatever I’m doing is working,” he told British reporters.

“In life, things just seem a lot better and that’s enabling me to get on with my job without having any baggage.”

Ferrari has played down rumours it is close to immediately ousting Felipe Massa, insisting it is possible the struggling Brazilian will still be in a red car next year.

On Twitter, the famous Italian team said the latest rumours – including a claim that former Virgin driver Jerome d’Ambrosio is a candidate to replace Massa in 2012 – are “funny”.

But it was Ferrari itself who fuelled the speculation, publishing a statement on its website that read like a warning to Massa.

“It was a very carefully-worded statement, wasn’t it?” said Telegraph correspondent Tom Cary.

“The way this crazy season is going, I really would not be massively shocked if they ditched him mid-season.”

The Swiss newspaper Blick said Monaco next weekend could be the 30-year-old’s last chance to up his game.

And the candidates are lining up.

“Ferrari knows that I’m ready. If they need me or they want me, then they will call me,” Adrian Sutil, who accompanied his manager to last weekend’s Spanish grand prix, said.

The Spanish newspaper El Mundo said some paddock pundits believe “the only reason” Massa still has its seat is because the “name Todt” – a reference not only to Massa’s manager Nicolas but to the FIA president – has a “protective arm” around him.

Ferrari spokesman Luca Colajanni told Brazil’s O Estado de S.Paulo newspaper this week: “Felipe has the full confidence of the team, starting with our president.

“We have not decided who will be our driver in 2013 but Felipe is not ruled out,” he insisted.

Indeed, while some believe Ferrari has hung a sword of Damocles above Massa’s head, others think the Maranello based team have been patient since the Paulista’s recovery from his near-fatal head injuries of 2009.

“We have no evidence that makes us think that Felipe has slowed down because of the accident. Zero,” Colajanni said.

F1 doctor Gary Hartstein agreed: “An experience like that (Hungary 2009) changes you, but you can’t say that’s why Felipe has not won again.”

Despite not topping a Friday timesheet in Barcelona, one specialist publication sees Lotus as the favourite for Spanish grand prix victory.

Germany’s Auto Motor und Sport said the ‘long run’ pace of the black and gold E20 was studied carefully after Barcelona practice.

“Kimi Raikkonen made a great impression on the critical soft tyres,” the report read.

“First, it (the field) is incredibly close. Second, Lotus could win its first grand prix here.”

If true, the former Renault team would become the fifth different winning constructor in the opening five races of the extraordinary 2012 season.

“Our biggest opponent for Sunday is not Red Bull,” an unnamed McLaren engineer is quoted as saying. “It’s Lotus.”

And another surprise pacesetter is Sauber. “Over 15 laps we were better than Red Bull,” team manager Beat Zehnder enthused.

“If everything goes right, we can be on the podium,” he is quoted by the Swiss newspaper Blick.

Agreed McLaren’s Jenson Button: “The Lotus, Sauber and Williams look very strong.”

But in reality, in F1′s new guise of 2012, no one knows what is going to happen on Saturday and Sunday.

“Lord knows what will happen here tomorrow,” wrote The Times’ Kevin Eason. “Well, perhaps He is the only one who does know what is going on — F1 hasn’t a clue.”

Romain Grosjean is a potential grand prix winner.

That is the claim of the Frenchman’s first F1 teammate Fernando Alonso, who shared the Renault team with Grosjean in 2009.

The Enstone based team, however, was imploding amid the crashgate scandal, and Grosjean struggled to perform after being drafted in to replace the sacked Nelson Piquet.

He lost the drive at the end of the season and then found himself in the odd situation of farewelling his girlfriend, the French F1 presenter Marion Jolles, as she departed for a grand prix.

“She was there and I was home,” Grosjean is quoted as saying in Barcelona by the Gulf Daily News. “Honestly, I thought it was over and I would never come back to formula one.”

But, now as the new reigning GP2 champion, he is back in 2012 at the wheel of Lotus’ black and gold E20 — a car tipped by many as the favourite for victory this weekend.

Many naturally tip Grosjean’s famous teammate Kimi Raikkonen as the most likely winner, but Spaniard Alonso rates the Swiss-born 26-year-old as well.

“When his car was not so good he was criticised a lot,” Alonso told RMC Sport, “but when he has a good car he does very good results.

“He has won GP2 and has a fantastic career. He has talent and I’m happy he went onto the podium (in Bahrain).

“He can win a grand prix,” the Ferrari driver professed.

Monisha Kaltenborn has revealed she has “very big plans” for Sauber.

Named by founder and team principal Peter Sauber as his forthcoming successor, the 41-year-old Indian is in effect already leading the Swiss team at grands prix.

She will take over in earnest at some point in the foreseeable future, thus officially becoming the first female team principal in the sport’s history.

“I have very big plans for the team,” she told the APA news agency in Barcelona.

“I am very happy with the trust that has been put in me,” Kaltenborn, whose current title is chief executive officer, added.

She said she is not bothered that she is not yet the team boss in title.

“For me, it’s never been important,” said the lawyer. “There are more important things.”

Mark Webber appears headed for a new contract with Red Bull, after receiving a clear vote of confidence from the energy drink company’s chief.

Following speculation the 35-year-old Australian could be headed to Ferrari in 2013, Red Bull team boss Christian Horner insisted Webber “is happy to be here, and we are happy to have him with us”.

And the Swiss newspaper Blick has revealed that team owner Dietrich Mateschitz, the billionaire mogul, is also happy with Webber.

“I hope that he keeps driving with us for a long time,” the 68-year-old is quoted as saying.

Ferrari might be gearing up to incorporate a ‘double-DRS’ setup aboard its improving F2012 car.

If true, the famous Italian team would be the first team to successfully emulate the controversial Mercedes system, which has been declared fully legal by the governing FIA.

Germany’s Auto Motor und Sport said a new rear wing was among the very last upgrades to be trialled by Fernando Alonso as the Mugello test concluded late on Thursday.

“The wing has only minor changes. You have to look closely,” read the report.

The magazine reported rumours that the wing might eventually accommodate the so-called ‘double-DRS’ or 2012-style F-duct, which would work in conjunction with a new and so far unseen front wing.

“That (wing) will debut along with a new diffuser and nose in Barcelona,” added Auto Motor und Sport.

There were happy faces in the Ferrari garage on Thursday, as – despite a minor off by Alonso – the upgrades appeared to work well.

“Barcelona will be a key moment in the season, but not a decisive one,” the Spanish driver insisted.

“It’s not a case that we will suddenly find ourselves back on pole position, because there is no magic button.”

Echoing the earlier words of Mark Webber, Alonso said the “fastest car” at Mugello this week was the Lotus.

Red Bull’s Dr Helmut Marko agrees: “It looks like Lotus are the quickest.”

Veteran Swiss correspondent Roger Benoit wrote in Blick newspaper: “Lotus, with Kimi Raikkonen in super shape, is the championship dark horse.”

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”.

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!”

Kimi Raikkonen can add a second title to his tally in 2012.

That is the claim of the 2007 world champion’s countryman Mika Salo, who now commentates on Finnish television MTV3.

In the fourth race of Raikkonen’s return to F1 from rallying, the 32-year-old last weekend challenged Sebastian Vettel for victory in Bahrain, finishing second for Lotus.

Five years after his title with Ferrari, he is 19 points from the head of the 2012 drivers’ championship.

“The most consistent team has been Lotus,” former grand prix driver Salo said. “They’ve been fast at every circuit so far.

“In that sense, Kimi’s situation looks very good. I would not exclude it at all that he will be fighting at the very end of the championship, if Lotus is able to maintain the pace of development.”

It is on Salo’s final point that Lotus’ 2012 season will really be made.

“They (as Renault) also began the previous season just as well, but soon after they were nowhere,” observed the Swiss commentator Marc Surer, speaking on Austrian television Servus TV.

“So the real question is ‘Do they have the resources to develop the car and stay where they are now?’”

Even if Lotus’ challenge fades, the future for Raikkonen – who has surprised some experts with his re-adaptation to F1 after two years of rallying – is bright, Surer insisted.

“I think he has shown everyone that he is still able to do just what he was doing before (leaving F1),” he said.

“He is a lot younger than Schumacher, and if you look at the past ten years, he is probably one of the best talents that we have seen in F1.”

Surer said he could therefore imagine Raikkonen leaving Lotus and returning to a ‘top’ team, but he wouldn’t know which one to recommend.

“Everything is so balanced this year that it’s impossible to pick a car that he could win the championship in.”

All this year’s title contenders know after four ‘flyaway’ races in 2012 is that they do not know what will happen in Spain next month.

“The only certainty is uncertainty,” read the German headline at Netzeitung.

With F1 generally regarded in the wider world as a sport with predictable results, this is an entirely new situation.

“The statistics show that it’s been nine years since there have been four different winners in the first four races,” said Ferrari team boss Stefano Domenicali.

Indeed, the famous Italian team as well as McLaren, Mercedes and Red Bull have won the opening races of 2012, and also with potentially winning pace have been Lotus and Sauber.

“More than that,” continued Domenicali, “you have to go back 29 years to find the last time four different cars won.”

One explanation is that F1 has never been more competitive, with plenty of well-oiled teams and no fewer than six world champion drivers on the grid.

But Domenicali thinks Pirelli is the dominant factor.

And not everybody is happy about that. Michael Schumacher told Bild newspaper that this year’s tyres degrade so fast that rubber “flies from the rim” if he pushes too hard in a corner.

“We drive around like the safety car. It is not a satisfying situation,” the seven time world champion said.

Pirelli’s motor sport director Paul Hembery is unimpressed with the rebuke, insisting that the Italian marque is only trying to “make tyres that make the races exciting”.

“We cannot take individual drivers into consideration,” the Briton insisted.

“It would be dead easy for us to make tyres that don’t break down. Then the top ten would also be the top ten in the race.

“But no one wants to see boring processions,” Hembery claimed.

Agreed the Swiss headline at Blick: “Pirelli is sweeping away the boredom”.

Indeed, not even the other Mercedes driver, Shanghai winner Nico Rosberg, agrees with Schumacher.

“It’s total chaos. You don’t know who is going to be fast at the next track,” he is quoted by DPA agency. “Formula one has become almost unlike any other sport.

“Yes, you cannot drive any laps any more at full throttle. Often, it’s like driving on ice. But that’s a big and an interesting challenge,” said the German.

Undoubtedly exciting for the fans, but the teams are having to adapt quickly. Italy’s La Gazzetta dello Sport said on Sunday that Vettel’s victory could mean Red Bull resumes its dominant grip on F1.

Dr Helmut Marko doesn’t think so. “We don’t even know who our opponents are!” he exclaimed.

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.”

The calamitous Bahrain grand prix saga has not jeopardised the island Kingdom’s future on the F1 calendar.

That is the strident claim of Bernie Ecclestone, after the F1 chief executive and FIA president Jean Todt displayed rare unity as they insisted the country’s civil and political problems would not affect the grand prix.

But amid the bubbling Bahrain saga, Ecclestone had suggested that Bahrain might face trouble when it comes to negotiating a new contract, with the existing agreement only set to extend for three more years.

However, when asked by Reuters if F1 is going to keep returning to Bahrain despite this year’s troubles, Ecclestone insisted on Sunday before leaving the Persian Gulf: “Absolutely. Forever. No problem.”

Like Todt, he even played down the damage done to F1′s reputation this weekend.

“I think it’s good because people talk about things, you know. You know what they say — there is no such thing as bad publicity,” said Ecclestone.

In truth, reputation damage has undoubtedly been done. But Roger Benoit, the veteran correspondent for the Swiss newspaper Blick, admitted he is dismayed with how politics interfered with sport so strikingly this weekend.

“On all continents, somewhere, all hell is breaking loose. And as a formula one reporter, you’re flying around this globe two or three times a year,” he wrote.

“We go to countries that are politically explosive. Where human rights are violated, where poverty reigns.

“But we hardly talk about it — not in China, India, Korea, Malaysia, Singapore or Brazil. In 2014, we’re going to Russia.

“Years ago, our circus happily danced around in apartheid South Africa, and the military dictatorship of Argentina.

“Formula one is pure entertainment. Detached from the problems of the world. But here, in Bahrain, every reporter entered the political field, whether he liked to or not,” wrote Benoit.

So that is why Ecclestone is unapologetic, after championing the Bahrain grand prix.

“Because, basically, the problems they have in Bahrain have nothing to do with F1,” the 81-year-old told El Pais newspaper.

“The relevant agencies gave the nod as far as security was concerned, and I think it is clear that they were not wrong.”

He also sees no problem with F1 being used as a political tool.

“Governments want to have an F1 race for the same reason as they want the Olympics. We come to agreements with the promoters and, if that’s good for the country, fine,” said Ecclestone.

Sauber has become the second formula one team to reveal a brush with Bahrain’s civil unrest.

Force India was involved in a Molotov cocktail attack earlier this week, resulting in two team members returning to the UK and Nico Hulkenberg and Paul di Resta sitting out the second practice session on Friday.

Now, the Swiss team Sauber has revealed it saw masked protesters throwing petrol bombs whilst returning from the circuit to their Manama hotel late on Thursday.

“At 20.50 the 12 mechanics, being on that minibus to the Novotel, noticed fire on the medial strip of the highway,” said spokesman Hanspeter Brack.

“On the opposite lane there was no traffic. The team members saw a few masked people running from there over to their lane where a bottle was burning as well.”

No one was hurt.

F1 chief executive Bernie Ecclestone on Friday played down the latest drama, accusing reporters of “wanting a story” and offering to ride in the cars with the frightened Force India team members if they are afraid of Bahrain’s night.

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.
