McLaren team principal Martin Whitmarsh is convinced Jenson Button is up to the challenge of ending Lewis Hamilton's recent charge.
Whitmarsh is in the fortunate position of having his two drivers out in front in the fight for the world title, with Hamilton 12 points clear of Button.
The momentum may be with Hamilton going into Sunday's German Grand Prix, but Whitmarsh does not believe Button will continue to let him have it all his own way.
“Jenson is second in the drivers' championship, has had two great wins this year and has proven he's a great racing driver, a great reader of a race,” said Whitmarsh.
“He will want to win this weekend, to move that momentum back in his favour, and that's just how it should be.”
