Vettel - "I have the feeling Brawn's were playing with us"

Brawn GP recorded a one-two victory in Melbourne, but it seems the former Honda team could have destroyed rather than simply beaten its competition.

BMW-Sauber figures expressed huge disappointment about Robert Kubica's late crash with Sebastian Vettel last Sunday, insisting the Pole could have raced up to eventual winner Jenson Button and passed him.

"That's interesting," Briton Button, 29, grinned as he reflected on his win in St. Kilda - a beach suburb near Melbourne - before having to jet off to Malaysia.

"I don't think Kubica has any idea about whether I was driving as fast as I could have," he added coyly.

Red Bull's Vettel, seemingly matching his Mercedes-powered rival as he ran second to Button for most of the 58-lap race, suspects the Brawn driver's hint is indeed true.

"I have the feeling they (Brawn) were playing with us," the German told Auto Motor und Sport.

An unnamed Brawn team figure is quoted by Britain's Guardian newspaper as also suggesting the Brackley camp did not display its full pace throughout the 2009 season opening race weekend.

"It is just foolish to just annihilate people all the time," he said. "I think we have a little bit in the bag. We've got good stuff coming and I think we have reason to be confident," he said.
