Nico Hulkenberg insists he is happy in formula one without his famous manager Willi Weber.

After a year on the reserve bench, the German returned to the grid in 2012 with Force India, but no longer represented by Weber, the famous former manager of the Schumacher brothers.

“There were a few reasons why I separated with Willi Weber,” Hulkenberg told spox.com.

“Now I’m doing it without some new management,” he explained. “I have assistants, because of course I can’t do everything by myself.

“It’s going quite well at the moment.”

Hulkenberg, 24, is not the only F1 driver without a manager, as Kimi Raikkonen now handles his own career.

“I have (also) taken Sebastian Vettel and Nico Rosberg as role models,” admitted Hulkenberg.

Whilst admitting the RB8 has “very nervous” handling, Sebastian Vettel insists there is nothing fundamentally wrong with the 2012 Red Bull.

The German looks likely to struggle to add a third consecutive drivers’ title to his tally this season, after slumping to just sixth in the points standings after the first two races.

In China, he has reverted to a launch specification of the Adrian Newey-penned car’s exhaust layout, whilst Mark Webber is plugging ahead with a further development of the Australia-Malaysia solution.

“There is no question of something (being) wrong,” Vettel is quoted in Spanish media reports as saying in Shanghai, “just a few things that are probably just not working in an ideal manner.

“The problem we have is that the balance of the car is not as good as we had last year. It’s not a question of downforce, but of ensuring that all the parts are behaving as a whole.

“That is what we are trying to achieve.”

Vettel dismissed the suggestion that because Red Bull’s cars are in two different specifications this weekend, it means the team has “lost” its way.

“I wouldn’t say that,” he said. “I firmly believe we have a very competitive car, at the moment we are just not able to take its full potential out.”

Meanwhile, the 24-year-old said he has spoken with Narain Karthikeyan, following their collision in Malaysia.

Vettel twice showed his Indian rival the middle finger, and described Karthikeyan – who was penalised by the stewards – as an “idiot”.

“I spoke with him and he apologised,” Vettel is quoted by Germany’s spox.com.

But when told that he was once a backmarker like Karthikeyan, the German insisted: “I was never as far behind as the HRT.

“Of course you have to drive your own race. But you still have to know what is going on around you.”

Jaime Alguersuari has offered a less than flattering opinion about the personality of his fellow Spaniard and F1 driver Fernando Alonso.

“He is cold (frio), very cold,” said 20-year-old Alguersuari, the youngest driver on the grid who races with the second Red Bull team, Toro Rosso.

“He is a man of few words,” he is quoted as saying by Dir Emotions.  “I have no relationship with him.”

Alguersuari also described the Ferrari driver and double world champion as “a great” F1 racer.

Alonso, 29, recently moved to clarify some misperceptions by revealing that when people actually meet him, they often remark that he is “nicer” than his media image.

The German-language spox.com compared Alonso’s apparent win-at-all-costs attitude with that of Michael Schumacher.

“In the media we read again and again things about ourselves that are not right,” said the Spaniard.

“People are making judgements from the outside, but that’s the business.”

Asked to clarify the misperceptions, Alonso said: “I am very calm and relaxed, even romantic.  Actually, I’m a normal guy.

“A little bit shy, but when everything’s right, that’s when the Spaniard in me comes out,” he laughed.

In Singapore last weekend, Ferrari team boss Stefano Domenicali agreed that Alonso is “cool and calm and sometimes difficult”.

And after back-to-back victories from pole, Alonso says he is on the top of his game.

“The F1 championship is very long compared to other sports so you can’t be completely fit, focused, motivated 100 per cent of the time.

“But now, in this part of the championship, I’m at a peak,” he is quoted in the Spanish press.

Rumours of driver movements within the top teams are yet again gaining traction.

Recently, a Spanish television station reported that, notwithstanding the existence of new contracts, Felipe Massa and Robert Kubica could be set to swap seats for 2011.

The Swiss publication Motorsport Aktuell is now reporting a similar rumour, whereby Massa would leave Ferrari at the end of the season to make room for Pole Kubica.

But the report said Brazilian Massa would be accommodated not by Renault but by Ferrari powered Sauber, where he drove as a rookie in 2002 and again in 2004-2005.

“Of course I read all the rumours,” Kubica said in an interview with spox.com, “but in the end the only thing is winning.

“We are all here because we want to win and you need the best car for that. Currently I’m at Renault and so I am focused on this team and on improving together.

“In 2011 we want to fight for the world title. We’ll see what happens next,” the 25-year-old added.

Kubica admitted that he would like to race for Ferrari one day.

“In karting, Formula Renault and F3, I’ve always been with Italian teams and I even lived for more than a year near Monza.

“Ferrari is a team unlike any other,” he acknowledged. “The emotion and the history is unique. I think every driver would like to drive for Ferrari.”
