Ross Brawn has paid tribute to Rubens Barrichello whose Indian summer in Formula One will continue with Williams next year.

Williams on Monday unsurprisingly confirmed veteran Barrichello and Nico Hulkenberg as their line-up for 2010, with Nico Rosberg and Kazuki Nakajima making way.

Although deciding not to renew Barrichello's contract, Brawn said: "Rubens was with our team for four years and we regard him as a highly experienced and talented driver whose contribution to the team over that period was significant."

Rosberg is almost certain to switch to Brawn GP to link up with Jenson Button, providing the new world champion can thrash out a deal with the Brackley-based team.

Button was forced to fend off a title charge from Barrichello after sweeping aside the Brazilian in the opening seven races when he was victorious in six of those.

The 37-year-old was forced to settle for third in the drivers' standings come the end of the season in Abu Dhabi yesterday, finishing 18 points adrift of Button.

Although deciding not to renew Barrichello's contract, team boss Brawn is delighted Barrichello is remaining in the sport.

"This year was a very special season for Brawn GP and I'm extremely proud of the spirit in which our drivers fought for the championship," he added. "Rubens contributed hugely to our success in the constructors' championship with two great victories in Valencia and Monza, along with numerous podiums, and he was a pleasure to work with."

Barrichello is the most experienced driver in Formula One history, having made 284 starts, and in joining Williams will now pass the 300-race milestone next year.

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."
