Button vows to be more aggressive

Button, winner of six of the first seven races of the season, has managed no better than fifth place in the last four events and saw Brawn team-mate Rubens Barrichello win the European Grand Prix to move back into second place in the standings.

Button finished in seventh place at Valencia, despite his team having returned to the top following a series of disappointing performances.

The Briton reckons it's time to be more aggressive, not only with his driving, but also with his strategies, if he is to stay on top of the championship table.

"It is better to be consistent and not crash, but if you are consistent and get two points it is not enough," said Button. "I am going to go to Spa and be more aggressive, for sure. In every way, not just driving, but with the strategy and with the tyres.

"It is where we have got to be, because otherwise it is going to be slowly eaten away. It is a very difficult season this year because we have had some really poor weekends and some really strong weekends, and this was the first time when we have had a strong car that I have not been able to get the most out of it.

"That is the most frustrating thing. We have to turn that around."

Despite his lack of results in the last few races, Button is still 18 points ahead of Barrichello with six races to go, having benefited from the poor race Red Bull endured in Valencia, where both Sebastian Vettel and Mark Webber failed to score.

The Brawn driver admitted he is surprised to have managed to keep a healthy lead after such difficult races.

And he believes he will continue to benefit from the rivalry between Webber and Vettel in the remaining races.

"Yeah, that is the pretty amazing thing," he added. "My best finish has been fifth in the last two. This one should have been a lot more, but it wasn't. I got two points though and I've got 18 points over Rubens. That is still a good margin but Rubens is very quick at the moment.

"As I've said before, we are in the same car and this is not a typical day for myself. I think we got very unlucky, which was caused by me making the mistake in qualifying. And we have got a 20.5 lead to Webber, and Sebastian is another five points behind him.

"The good thing is that the Red Bulls are still going to be fighting. They are going to be quick for sure over the next few races, especially the next one at Spa, although I don't think the McLarens will be as quick as they were here.

"I think we have sorted out a few of our issues, and we have some updates, so Rubens and myself will be very quick at Spa.

"I just hope I can get a good lap in qualifying, as I have been doing most of the season, because two-and-a-half tenths can be three places on the grid, so you need the perfect lap. I enjoy Spa and I think we can have a good weekend there."
