Williams have confirmed Rubens Barrichello and Nico Hulkenberg will be their drivers for the 2010 Formula One season.

The news has been widely anticipated for several weeks, with the duo replacing Nico Rosberg - set to take up Barrichello's seat at Brawn GP - and Kazuki Nakajima.

Team principal Frank Williams said: "Rubens needs no introduction. He is not only the most experienced driver in Formula One but a passionate and talented driver who fought hard for the championship this year.

"Nico won the GP2 championship this season as a rookie and has previously won the F3 Euroseries, Formula Master, A1 GP and Formula BMW Germany."

Barrichello is the most experienced driver in Formula One history, having made 284 starts, while Hulkenberg is a rising star, who has been Williams' test and reserve driver this year.

Williams added: "Nico Rosberg and Kazuki remain our drivers until the end of 2009 and I would like to take this opportunity to thank them for their contribution to the team.

"Nico and Kazuki have represented Williams and our partners with dedication, discipline and skill and we wish them every success with their future endeavours."

Barrichello, 37, has 11 grand prix wins to his name for Stewart, Ferrari, Honda and Brawn and finished third in this year's drivers' championship behind Jenson Button and Sebastian Vettel.

Barrichello insisted on Thursday that Williams are a team "anyone would look at", because they are "one of the best teams out there, and are on their way up."

Williams, though, could only finish seventh in the constructors' championship this year - Nakajima ending the season with the unenviable record of failing to score a point from the 17 races.

The team have not won a race since the 2004 Brazilian Grand Prix, yet Barrichello claimed his motivation for carrying on racing is that he wants to win.

"I have a lot of passion for speed, for overtaking, for the things that pump me up, the challenge of winning," Barrichello said. "I want to go on and have a chance to keep on winning."
