Vettel 'comfortable' with Red Bull deal

Some media reports - based on quotes extracted from an interview with Red Bull boss Dietrich Mateschitz in the Allgemeine Sonntagszeiting paper - had focused on the existence of an exit clause in the contract permitting Vettel to leave if Red Bull Racing failed to supply him with competitive machinery.

But, speaking to reporters in Melbourne on Thursday, Vettel emphasised that he is happy with his decision to stay.

"It's not something you decide in one day," he said. "Well, at least I didn't - there are a couple of pages on these things [contracts], rather than one line which you either agree to or you don't. Basically, though, I feel very comfortable in the team and there's nothing that I'd like to change.

"We have a common target and we've achieved a lot together in the past, racing against the best teams and drivers out there. My number one priority is to win races and to be at the top of the field.

"Don't get me wrong - I love to drive but I also love to compete. And I'm very confident I can do that with the team I'm in."
