Kazuki Nakajima - 14th:

"Although we are not expecting much here, today didn't go too badly. Certainly compared to Spa, I think I will be more competitive here, although it is perhaps too early to say how we will go in qualifying. We worked hard today and tried many different technical options, but importantly found some positive direction, so I think the main priority to is maintain this progress tomorrow."

Nico Rosberg - 17th:

"The most important job today is to find the compromise between top speed and grip and it's not easy to arrive at the optimum downforce level. We were very slow on the straights this morning, so we looked at this and we have found a good solution. Tyres are just as important and we have completed a good test, from my point of view the direction is pretty clear. The rest of our running time was focused on aerodynamics and we found some good direction, but despite doing some good homework, it is going to be difficult for us here and it won't be an easy weekend. To repeat the Spa performance of making into the top ten in qualifying will require a helluva lap, but that's not to say we can't pull it out of the bag!"

Patrick Head - director of engineering (Williams F1):

"We've been doing our homework on the tyres today. Both tyres look pretty good and we've gathered a lot of data today to go through to optimise our set-up for qualifying tomorrow."
