A spokesperson for Rubens Barrichello has denied suggestions the Brazilian veteran has already signed to switch to the Williams team in 2010.

The 37-year-old, not only the oldest active driver in F1 but also the most experienced in the history of the sport, is still in contention for the 2009 title but reported to be likely to leave the Brawn team after the Abu Dhabi finale.

Specialist reports have said his move to replace Williams' departing Nico Rosberg is all but signed, but a spokesperson said it is "only speculation", according to the Folha de S.Paulo newspaper.

"We do not have anything to say about that," the official added. "Season 2010 is not one of the things that we are deciding upon now."

However, the same source admitted that Barrichello is in talks with "several teams" in addition to Williams and Brawn.
