Red Bull contract not open door for Vettel

Helmut Marko has played down any suggestion Red Bull has simply left the door open for Sebastian Vettel to be poached by a rival team.

As the reigning champion and 2011 title leader recently signed up through 2014, team owner Dietrich Mateschitz admitted that if 23-year-old Vettel wanted to go to Ferrari or Mercedes, then "we would let him".
