Germany’s Nico Rosberg will race for Mercedes next season, the team that this year won the Formula One championship as Brawn said on Monday.

Rosberg has spent the last four years competing for Williams. Yet to win a race in 70 starts, the 24-year-old son of Finland’s 1982 champion Keke finished seventh overall this season. His best finish is second place in Singapore in 2008.

Mercedes took over the British-based team last week, renaming it.

Brawn, who emerged from the remains of the Honda team, won both titles in their debut season but Britain’s world champion Jenson Button has joined McLaren while Brazilian Rubens Barrichello has taken Rosberg’s place at Williams.

“I am really happy to be a part of the Silver Arrows re-launch in 2010 as a driver for Mercedes,” Rosberg said in a statement.
