China Sunday quotes: Williams

"The other significant part of the race for me was the last period when I had to work hard to keep quite a few cars behind me and defend my position, and I was pleased that I succeeded in this."

Nico Rosberg - 15th: "My race was not good today, but it wasn't for lack of trying. We ran a different strategy to Kazuki just to see if we could generate some advantage, but it didn't pay off and it wasn't a lot of fun driving at the back. It didn't really represent our capability as our pace was okay and we were the tenth fastest car.

"I made a few passes but it was quite difficult to overtake as our top gear was too short. From here we can look forward to Brazil which should be a bit better for us, and then after this season working with the team on a positive winter in order to move us forward for next year."

Patrick Head, Director of Engineering: "It was not a strong result today, but I thought Kazuki did a good job defending his position. As we qualified poorly, we had to do something a bit adventurous with our strategy, so we split our options on the cars, but unfortunately the two stop route we took with Nico didn't work.

"Having not attended a race for some time, I must say I am very impressed with the professionalism of the race team. The car is reliable, but the problem remains that on this type of circuit it is just not quick enough."
