Di Resta to discuss Force India future this week
The new DTM champion served as the Silverstone based outfit's reserve and Friday driver in 2010, and is a contender for a race seat next year.
But also in the running is ousted Williams rookie Nico Hulkenberg, while Adrian Sutil is expected to be retained and Vitantonio Liuzzi has a firm contract for 2011.
Scot di Resta's manager Anthony Hamilton is confident: "There hasn't been one bit of negative information from the team about Paul.
"He has done a great job, the team love him," Hamilton, father of McLaren driver Lewis Hamilton, told the BBC. "He's a champion and a leader.
"Nothing has changed; he is still a contender for a race seat. We are very positive," he added.
It is believed Sutil will have one seat in 2011, while the other will be occupied by either di Resta or German Hulkenberg after Liuzzi's contract is bought out.
