Jacques Villeneuve has admitted he is not yet in talks with any teams about making a return to formula one.
The French Canadian, who came close to driving for the hopeful Serbian outfit Stefan GP this season, said last weekend he will make a final effort to find a seat for 2011.
"I am working on it more than ever, and for that reason I have postponed a participation in the NASCAR circuit," 1997 world champion Villeneuve, who turns 40 early next year, said in an interview with Austria’s Salzburger Nachrichten.
Stefan GP, however, seems unlikely to be on the grid any time soon, and Renault team boss Eric Boullier said recently that he is not interested in signing Villeneuve.
Asked if there are already "concrete negotiations" with any teams, he answered: "No, nothing concrete, because it’s too early in the season.
"There are some positive contacts. If the Stefan project had worked out, I would be driving in F1 already this year."
Villeneuve acknowledged that a place with a top team is not initially likely.
"I have a longer term plan," he said. "The most important thing is to get inside, and then you can look around and find the right place."
