Rubens Barrichello, WilliamsRubens Barrichello believes he will be back with Williams next year despite the uncertainty over his future in Formula 1.

The veteran Brazilian is yet to secure a race drive for 2012, with Williams still evaluating candidates to fill the seat. After finishing the Brazilian Grand Prix in 14th position, Barrichello said he is confident he will be racing in F1 next year despite all the speculation about his future.

"I want to thank the team for all their hard work this year," said Barrichello. "We have had a tough season but we've pushed together. There's been a lot of talk over the weekend, but I believe I will be back again next season."

The Brazilian admitted a race gamble did not pay off after the rain never hit the track, but he still believes his car was not fast enough to score points.

"We thought it was going to rain today so we were running a long first gear. I started at the bottom of the hill, and as it was a dry start, I slipped back. It was a fun race but we don't have a car that can finish in the points just yet."

Teammate Pastor Maldonado retired from the race after losing control of his car on lap 27.

"Our overall pace during the race was fine, but the rear wing setting slightly held us back on the long straight," he said. "My retirement came after I passed Senna on lap 26. The car had too much oversteer and I just lost control of it."
