Button: Brawn has regained advantage

Jenson Button says his Brawn GP team has regained its advantage at the head of the field after dominating the Spanish Grand Prix on Sunday

Button led team-mate Rubens Barrichello to the second one-two finish for Brawn this year, the Briton scoring his fourth victory in five races.

Now Button is 14 points ahead of Barrichello in the standings, while Brawn leads Red Bull by nearly 30.

The championship leader, who had claimed earlier that he thought Red Bull was ahead of his team in terms of performance, reckons the updates introduced in Spain have moved Brawn back ahead.

"It is a dream come true so far this season, even when times are tough we seem to be able to get the wins," said Button. "When it goes well it goes well, last year when it went bad it went bad.

"I feel on top of the world at the moment. The team have done a great job and with this package you could see we have got our advantage back again, and thanks to Mercedes as we couldn't do it without them."

Button revealed he was originally going to stop three times, like Barrichello, but the team decided to switch his strategy during the race, a move that put him clearly ahead of the Brazilian.

The Briton admitted winning in Barcelona, a difficult track for him, is a real boost for the rest of the season.

"We were both going in that direction but they switched me to two stops to cover all our bases. Three stops was the quicker strategy, we thought. I wasn't sure about going to two stops because when I put the fuel on board it felt very heavy.

"I didn't think I would come out ahead of Felipe and Sebastian but I did. So I put my head down and concentrated on going as fast as possible.

"Coming back to Europe and winning at Barcelona, a circuit I have always found tough, is great and gives me a lot of confidence for the rest of the season."
