Nick Heidfeld is in talks with Renault regarding a 2011 race-seat, a move that would once again see him partner Robert Kubica.
With Kubica confirmed for next year's Championship, Renault are currently debating whether or not to keep rookie driver Vitaly Petrov, who has scored just 19 points to his team-mate's 126.
One driver believed to be in the running is Heidfeld as the German, who started this season as Mercedes GP's test driver before switching to Pirelli and then to a Sauber race-seat, looks for a full-time drive for 2011.
However, the 33-year-old admits Renault may be looking for more than just talent.
"At the moment it's my last race for Sauber but I've thought that a couple of times before!" he told ITV when asked about 2011. "So you never know what's going to happen...
"For next year obviously there are many seats already gone. I'm still in talks with various teams - also with Renault, as (team boss Eric) Boullier confirmed.
"That would be the best opportunity but it's far to say that it's obvious that it's not the only thing (that) they are looking for is talent, what you can give on the circuit.
"They have Vitaly in the car, who has strong arguments but looking at his performance on track this year we know what those arguments are."
When questioned about how his rates his chances of racing for Renault, he said: "I know for myself, but I won't give away all the insight I have there."
