F1: Coulthard rubbishes Button bid

David Coulthard has rubbished Jenson Button’s chances of ending his reign as Britain’s number one grand prix driver - even if his own hopes of world glory look grim.

The 31-year-old Scot is confident he can see off the challenge of his younger English rival this season despite being out-paced by Button’s Renault for the first time in the San Marino Grand Prix in Imola.
