China Sunday quotes: Williams

"For the first few laps, they were good. It looked like the way to go so I was quite pleased, but then unfortunately more rain came and it was all over again. Bahrain is only a week away and a good result, which everyone in the team deserves, is overdue."

Kazuki Nakajima - DNF: "I had a transmission problem today so unfortunately I couldn't carry on with the race. It was very difficult out there with really poor visibility. There was a lot of standing water and it was hard to keep the car on the track, particularly on the exit of the last corner. I made some mistakes but it was the same for everybody."

Patrick Head, Director of Engineering: "We thought the safety car would stay out for longer than it did at the start of the race so we decided to pull Nico in early to fuel him up. It turned out to be the wrong call as the safety car came in just one lap later. We then struggled for pace against Alonso who had done the same as us. We had what appears to be a gearbox failure on Kazuki's car which forced us to retire him.

"It was not a good performance by us today. We made some wrong calls and we will have to look at the circumstances and improve for the future. It's also very unusual for us to have a retirement for a technical failure. We will now look forward to a much better performance in Bahrain. On a separate note, the team is saddened by the unexpected death of Jim Douglas. With Williams since the early days, Jim was a stalwart in our machine shop for 28 years."
