No personal sponsors for champion Vettel

Sebastian Vettel enters the 2012 season with a clean sheet when it comes to personal sponsorship.

The German recently filmed a television commercial for the dandruff shampoo ’Head and Shoulders’, but Germany’s Bild am Sonntag newspaper reports that he has not extended that deal.

"It is important to me that a brand is perfect for me. It is not my goal simply to make as much money as I can," said the Red Bull driver.

Jenson Button filmed a similar shampoo commercial recently, and was widely ridiculed for his performance.

"Of course, I’ve had a little bit of mickey-taking from doing the advert," Vettel admitted to the Sun.

"At least I never took my shirt off - I think Jenson did - but you have to be able to poke fun at yourself."
