ABU DHABI, United Arab Emirates — Nico Rosberg has confirmed that this weekend’s Abu Dhabi Grand Prix will be his last with the Williams team in Formula One.

Rosberg would not say which team he would join in 2010, with Brawn GP or McLaren thought to be the major contenders. Much of that will rest on Mercedes’ decision on its future ownership stakes in the two teams.
Rosberg said he was eager to join a team that had the potential to win races next season — something he thought was beyond Williams.
Brawn GP driver Rubens Barrichello has held talks with Williams about joining in 2010 and is considered the most likely contender to replace Rosberg.
