Thursday practice for WilliamsF1

Juan Pablo had previously expressed his view that he should be able to challenge for a win. How well both drivers perform in qualifying will determine what chances they have of winning.

Juan Pablo said, when interviewed on Wednesday: "The car has shown a lot more potential. Last week in the test it showed more promise again and we have got more things here so we are really heading in the right direction. The car is a lot more competitive and it has been getting a lot more competitive race by race. I think the only race we struggled was Barcelona, the others have been pretty competitive and I think here should be a really good race for the car.

Last year we were on pole and I think this year with a shorter wheelbase it should be a lot better, it should go through the slow corners a lot better and it should make a better time so hopefully we will be able to challenge for a win here."
