Red Bull boss Dietrich Mateschitz has admitted that an exit clause has been placed into Sebastian Vettel's new contract with the F1 champions, although he doesn't expect it to be needed.
Vettel agreed a new deal with the team last week which will run through to the end of the 2015 season, which should go some way to ending speculation linking the German with a move to Ferrari at some point in the coming years.
Speaking to the Allgemeine Sonntagszeiting
'paper, Mateschitz said he was hopeful that the new deal would put an end to speculation about Vettel's future but hinted that the team would consider letting him go before his contract expires if it didn't perform on track.
“[We have done the deal] so that he can feel secure at least for a while, but also to put to an end the 'hunt' of the other teams that often came close to the boundary of reasonableness," he said.
"[However] If we cannot give Sebastian Vettel what he needs and he asks us, despite his contract, to let him go, I can not imagine that we would not agree.”
Mateschitz was also quoted as saying that the exit clause in Vettel's new deal was a 'formality but is hardly necessary'.
