Barrichello frustrated by troubled race

Barrichello, starting from third position, lost all his chances of a good result when he nearly stalled at the start, when his anti-stall system kicked in due to what he said was a problem with the clutch calculations.

As he tried to regain ground, he made contact with Heikki Kovalainen and Adrian Sutil, and then retired with gearbox problems.

Meanwhile, team-mate Jenson Button cruised to his sixth win in seven races.

Barrichello, now 26 points behind Button, admitted he was frustrated that all the problems hit his side of the garage.

"It appears to be a gearbox problem," Barrichello told the BBC. "The one that I had on the start - same as Australia, when I dumped the clutch the anti-stall came in and it was the wrong calculation for the clutch once again on my side.

"With the anti-stall I couldn't get going and then, to complicate things, I was on the rev limiter halfway through the straight, which didn't make my life easier because I had to compete against cars with KERS and I had to force my way around. That's a race like this.

"It's just frustrating because it has been happening too much on my side."
