Sebastian Vettel has refused to rule out one day driving in formula one for McLaren.

The British team's boss Martin Whitmarsh said recently he is still interested in securing the young German's services, despite recently slamming him as a "crash kid" after his collision at Spa with Jenson Button.

Whitmarsh admitted he tried to sign Vettel as Fernando Alonso's replacement at the end of 2007, but found the rookie tightly under contract to Red Bull.
