Nick Heidfeld is confident he will be able to continue competing in F1 next year, what will be his eleventh season at the pinnacle of the sport.

The BMW Sauber F1 refugee has been linked to Mercedes Grand Prix recently - formerly 2009 F1 Constructors' Champions Brawn GP - however, while he is believed to be one of the favourites to team up with Nico Rosberg, the German has yet to agree terms.

Indeed Mercedes are also rumoured to be in negotiations with record-breaking multiple F1 World Champion Michael Schumacher and it is also thought that Robert Kubica could be an option too - although that is dependant on what happens with Renault F1, who the Pole has a contract with.

"I am still in promising discussions," Heidfeld told Rheinischen Post, when asked about his plans for 2010.

"There are still teams with free cockpits and I hope I can be with a good one that can win races."

Heidfeld, who made his debut in F1 with Prost in 2000, has yet to win a race - although he has been on the podium several times, and was second at the Malaysia Grand Prix at the start of '09.

Pressed on which teams he is in talks with, Heidfeld noted that Mercedes is his preferred choice although Sauber is also a logical destination given he has spent most his career with the Swiss-based outfit.

"Whoever knows F1 knows that of those with free cockpits, Mercedes offers the best chance to be in the front," he added.
