Rosberg confirms he will leave Williams

Rosberg has been linked with a switch to the Brawn GP team for several weeks, and he has made it clear he wants to be driving a winning car in 2010.

The 24-year-old confirmed in Abu Dhabi on Thursday that he is to leave Williams after his current contract ends.

"It is my last race for Williams," said Rosberg. "And that is it really. It is a bit strange because for four or five years it is the only team I have worked with, so it has been a long time.

"I get on with everybody really well, obviously, and a lot of respect has built up - with the mechanics and everyone. So it will be quite strange to leave.

"I can also use this opportunity to thank the team, because all in all I think they have done, for my career, a lot of good. Especially Sir Frank [Williams], Adam Parr, Sam Michael and Patrick [Head], they supported my career all these years. So it is a big thank you to them."

He added: "I don't want to talk about my future. I just want to say that I won't be at Williams, because that is for sure."
