Sep.27 (GMM/Inautonews.com) Paul di Resta’s manager thinks the rookie Scot has done enough in 2011 to secure his seat at Force India for next season.

But team boss Vijay Mallya has told the 25-year-old, as well as his current teammate Adrian Sutil and also reserve driver Nico Hulkenberg, that he will only decide the 2012 lineup in mid December.

Di Resta’s manager Anthony Hamilton admitted the driver is not guaranteed a race seat next year but he did reveal a contract option that includes 2012.

“Naturally we’d all like to know now where we stand, but there are option dates in the contracts, and there is another month or so to go before they can be exercised,” he is quoted as saying by the Daily Mail.

“I’m confident they’ll be exercised on the date in question – if they’re not then I’ll be very upset – but I’m sure everything will work out well for Paul,” added Hamilton, the father of McLaren driver Lewis.
