Barrichello says he has no doubts he will be in F1 in 2012

Barrichello is still in talks with Williams over a deal for next year, but speculation suggests other contenders for the seat are Adrian Sutil, Bruno Senna and Giedo van der Garde, who would arrived at the team with financial backing.

The Brazilian suggested he would only stay at Williams to have a more competitive season than in 2011, but he is sure to be in F1 next year.

"No, it is not going to happen," said Barrichello when asked if he was worried about not being in F1 next year. "I feel that in a way that I have to put everything into contest as well. I have to see how competitive everything is.

"A year like this, to be working for another year like this on my 20th year, I need something better. I feel the team is doing better with the engine change and the personnel change and everything, so I can see a good light at the end of the tunnel but I just want to continue because people want me to and they know I can win.

"Other than that, I will stay home and take care of the kids and winning my internet games. I already won this weekend my first virtual race, which is great!"

The veteran racer admitted he would have liked to have a deal for next year already, and says he is working hard to finalise something.

He added: "We are talking day by day. We just need to see. I wish we had done a deal already but it is taking a little longer, but so far there is nothing else to add, I am just working very hard to see what we can do as soon as possible.

"It is very flat in a way. I think that the team is taking everything into perspective, they know what I can offer. There is nothing else I can report, really. I am still waiting."

The Williams driver, who has scored just four points this year, is staying cautious about his chances for this weekend's race at Monza.

"It depends on what we have made as a team for here - the rear wing is that, and if it doesn't work it is the wing, but if it works that is the wing too, so we are very hopeful we made it quite well but we will wait and see for tomorrow. If you walk down the pit lane you see wings that are this big and wings that are small - it is very difficult to know."
