Sam Michael, Technical Director, WilliamsF1: "It's disappointing to have neither car in the final ten - a couple of tenths takes you a long way. However, we are confident of having a good race pace and using a good strategy tomorrow."

Mark Webber: "We got a bit of idea in testing that maybe it was going to be a little bit difficult for us here, but you only really confirm this on the day, and we found out today that we are just a sniff away from getting into the top ten. This is the first time this year that I didn't make it into the last ten by a small margin, but unfortunately we are not quick enough over one lap."

Nico Rosberg: "We still seem to be missing something to get qualifying right and making it into the top ten and this is something we need to work on. Our race pace so far this season has been quite alright though and I think tomorrow we should look quite good, especially with respect to our tyres. Both Mark and I are in good shape to collect some points in the race and we proved at the Nurburgring that we are able to make up positions into the points, even from the back of the field."

Sean O'Mahony, Principal Engineer - F1 Race Engineering, Cosworth Ltd: "Today was fairly uneventful on the engine front - there were no reliability issues in any of the sessions. On the calibration side, we carried out some fine tuning of the maps we developed yesterday and made an improvement in the low engine speed range. Hopefully we will see the benefits of this work tomorrow."
