Paul di Resta is working on the new 2012 car for Force India, but insists he "can't say anything" about his future with the team.

Force India has yet to announce its driver line-up for next season, with a decision expected by the end of this week. Di Resta is vying for a place along with Adrian Sutil and Nico Hulkenberg, with Sutil reportedly the most likely to miss out. When asked by the official Formula One website if he would definitely be racing for the team next season, di Resta refused to comment but did admit he was working on the 2012 car.

"I can't say anything," di Resta said. "The only thing that I can say is that I am still working closely with the team and helping with the new car. I will do some simulator work over the next week and hopefully by then (Force India team principal) Dr Mallya and his board will have made up their minds about their 2012 driver line-up. Certainly I would be very proud to stay with them for another year. They have shown a lot of respect for me and a lot of faith in me. They've given me the opportunity of a lifetime and I am very thankful for that."

Di Resta was also asked if he had a backup plan in case he was to lose his seat, and said that it was something that his manager would have worked at on his behalf.

"I don't think that this is something that you want to think about, but sure you have to think about a worst-case scenario - and thank goodness I have Anthony [Hamilton] doing that for me. That's what he is employed to do."

If he was to stay, di Resta said that the aim would be to overhaul one of the teams ahead of Force India in the constructors' championship.

"In terms of what we wanted to achieve, Force India finished sixth in the constructors' championship which is the best they've ever done. So that is very rewarding as it secures a bit more infrastructure and definitely changes the goals for next year. The next ambition will definitely be to finish fifth and I hope that I am part of that journey."
