Rubens Barrichello says he is keen to remain on the F1 grid next season, even if he isn't retained by Williams for the 2012 campaign.

The Brazilian has endured a tough year with the uncompetitive FW33 and has managed just two points finishes so far with four races of the season to run.

On only three occasions since making his debut back in 1993 has the Brazilian ended the season with four points or less, but question marks are now being raised about his future in the sport - with a decision over whether he stays with Williams yet to be taken.

Even if Williams elect to release the most experienced driver in the history of the sport, limited options are available elsewhere and Barrichello said he was keen to extend his career into a 20th year if he could find a competitive drive - be that with Williams or elsewhere.

"Whatever it takes, wherever - I want to be racing next year," he was quoted by AFP. "So I am talking to the whole paddock and the situation here is no different, they know what I would like to have next year - and the only thing I would like to have next year is a competitive car."

Barrichello expects to know his future with Williams before his home race at Interlagos in late November.
