Martin Whitmarsh believes Jenson Button's lights to flag Belgian GP victory has silenced all those who wrote him out of this year's title race.
Heading to Spa many were asking McLaren if it was time to ask Button to give up on his own title bid and support his team-mate's. The team, though, said no.
McLaren were vindicated in that decision on Sunday when Button stormed from pole position to the chequered flag, never once reliquishing the lead as he claimed his second win of the season.
"To be honest he was cruising for most of that, looking after the car and looking after the tyres. Absolutely faultless. Just a dominant, faultless display," Whitmarsh told Sky Sports News.
"He has just reminded all of those who were writing him off just a few races ago what a great driver he is. A fantastic result and a great job by the team."
