The Williams driver Nico Rosberg has announced he is leaving the team after Sunday's Abu Dhabi Grand Prix. The German refused to confirm where his location for 2010 is going to be, though he has been heavily linked with Brawn GP in recent weeks, but said: "It is my last race for Williams. 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." Rosberg made his debut with the team in 2006 and has had a strong 2009 season, scoring 34.5 points to leave himself seventh in the championship. "I would say it has been a good season," he added. "I would say that the team has given me a good car this season, which has been important for me because it has given me the opportunity to raise my share value, and gave me a great opportunity for next year to have a chance to get a winning car to win races - which is what I would like to do. "For me it has been a good season, and the team gave me a good car."
