Button Confident of Improvement

The Briton had the most of a new aerodynamic package on his BAR007 to set the fourth quickest time in this morning's practice session and, although a lowly 17th in the afternoon, he is upbeat because he knows there is plenty of room for improvement.

"The car felt like it had really low grip," he said. "We have got some balance issues as well, which realistically is a good thing because we can look at the car tonight and make improvements - instead of just having low grip like we have had before.

"We can really work with the car now and make the difference. It is not all bad."

Although the season has ultimately proved to be a disappointment for Button, he is confident that the team will be stronger in the final three races than they has been so far. In particular, he thinks the team can establish themselves in front of Ferrari and Toyota.

"I think we are going to be competitive against most teams like Ferrari and Toyota, but I think Renault have actually also made a good step forward with their car.

"Supposedly that is about half a second, so that is going to be slightly different. Our long runs are not too bad and that is what you need here, you need the consistency, so at least we have that."

Apart from his own hopes for the weekend, Button also is keeping his fingers crossed that the drivers' title fight is not resolved in Brazil.

"I hope the Championship is not decided here because we still need the excitement in the final two races and I don't think it will be decided here," he said.

"You know, I am looking forward to the last two races, it is obviously leading towards Alonso winning the championship but I still think Kimi has a chance."
