Belgium Friday quotes: Williams

"Unlike the last few races, however, the tyre choice seems to be pretty clear, so we can concentrate on other matters. We definitely have some hard work to do tomorrow morning to try and find a bit more for qualifying."

Alex Wurz - 16th: "It was a pretty tough day today and everything seemed to be difficult with the car and its setup options. We had a similar set of issues here at the Spa test, so we will have to work hard to change this.

"That said, the last few things we tried at the end of the day seemed to offer a better direction, so I hope we can undo these knots and make some progress tomorrow."

Sam Michael, Technical Director: "We ran through all of our programme today, although much of the work on systems we completed at the recent Spa test anyway. We have a lot of work to do here overnight as we are not as competitive as we have been in recent races, but we will see a clearer picture tomorrow. Our focus will be to get as much performance as we can out of the cars tonight."
