China Sunday quotes: Williams

Nico Rosberg - 16th: "It didn't quite work out for us today. I had a poor start which dropped me back, but then it was working pretty well for me in the wet and I passed several cars. In the next stint, we had switched to dry tyres and we had the same problem we experienced yesterday in qualifying with the tyres.

"On lap 29, I got a left rear puncture at the end of the straight, but I am not sure what caused it as I didn't make contact with anyone else. Obviously it cost me to come in for an extra stop and that was the end of my race. I am now looking forward to Brazil and to end this season with a good result."

Patrick Head, Director of Engineering: "Our grid position rather dictated our race, but the conditions were difficult today and we might have been luckier. Nico was certainly driving a very good race and overtaking cars but he sustained a puncture which also damaged some bodywork.

"As a consequence, he had to make an unscheduled stop without which it was quite possible he would have been among the points. As it was, we sent him out on the wrong tyres for the conditions and that was that.

"Alex's race was dictated by a poor grid position. The race was disappointing for both the drivers and the team. I must say congratulations to the Toro Rosso drivers who I think both did a good job."
