Bahrain Friday quotes: Williams

"Over the two sessions we made some very big set-up changes and I think we've gone into the right direction. It's getting very close with a lot of people in the midfield, but I think we have a good chance to do well this weekend. It was also productive to be reliable today which meant plenty of track time."

Kazuki Nakajima - 8th: "Today we didn't have any problems, so we could use all of the practice time which was great. Initially in the morning session, I struggled a bit, but in the afternoon, we made a big set-up change which was very positive. We have a bit more work to do tomorrow, but it is a good start."

Sam Michael, Technical Director: " We had a good first day's practice with no interruptions from a reliability point of view, and that enabled us to get through a full programme of set-up changes, tyre work and checking cooling and brakes. We will now work on qualifying performance for tomorrow."
