Nico Rosberg has added to Rubens Barrichello's denial that Williams has now settled on a driver line-up for the 2010 season.

It is heavily rumoured that the German and Brazilian drivers are set to swap seats at the end of this season, with 24-year-old Rosberg headed to Brawn and the Brazilian veteran to fill his spot at the Grove based team.

Brazilian media reports this week said the deals are done.

"I have spoken with Frank Williams and I know that absolutely nothing has been completed," Nico Rosberg is quoted by the EFE news agency as having said in Sao Paulo ahead of this weekend's Brazilian grand prix.

37-year-old Barrichello however admitted that talks are taking place.

"I haven't signed any papers, but that it's true there are talks with Williams and with Brawn, there's no doubt," said the Brawn driver.

In the midst of a title fight with his teammate Jenson Button, he indicated he is delighted with his current situation, after his future appeared particularly dim prior to the 2009 season.

"Today I feel very honoured that there are teams trying (to sign me) and that my situation is a lot better than for some time," Rubens Barrichello said.
