Vettel denies Ferrari deal
Sebastian Vettel can see no reason why he would want to quit Red Bull, despite the apparent existence of a get-out clause in his current contract.
Speculation has surfaced Vettel has already signed a pre-contract agreement to join Ferrari in 2014, a claim strongly denied by the 24-year-old.
Speaking to German newspaper Bild, Vettel said: "I know nothing about it. I've never signed anything."
Vettel, who has a contract with Red Bull through to the end of the 2014 season, instead is happy with life at the Milton-Keynes based team who have made him champion the last two years.
Although the situation could change over time, for now Vettel told Autosport: "I've been wearing a Red Bull helmet for almost my entire career.
"It is difficult to imagine another kind of life if you are so used to it.
"It would be like when you turn 18, 19, and you move out of your family's home.
"I am very happy where I am right now and I don't want to move on to anywhere else."
However, according to Red Bull advisor Helmut Marko, the right-hand man to owner Dietrich Mateschitz, Vettel has an opportunity to leave under the right conditions.
Marko told Bild: "2013 is fixed for us. For 2014 there is a performance-related clause in his contract - for him and for the team.
"It depends on the rankings in next year's world championships.
"If Vettel and Red Bull slip in the drivers' or constructors' championship, he could go."
