Ralf Schumacher is close to agreeing a deal to remain in the DTM with Mercedes, according to the manufacturer's motorsport boss Norbert Haug.
The six-time grand prix winner has raced in the German series for the past two years, beginning in a one-year-old car with Mucke Motorsport before graduating to the front-line HWA squad for 2009.
While Schumacher has struggled for results so far in his DTM career, with a fifth place at Dijon last year his best finish to date, Haug is optimistic that the 34-year-old will return for a third season.
"Ralf would like to continue his DTM career and we also think that the chances of continuing our co-operation look promising," Haug told the DTM website. "I think that we have come close to making a decision. It will be announced as soon as it has been made. Currently, however, the deal is not yet home and dry."
Haug added that talks were still taking place with David Coulthard following his two tests with Mercedes in recent weeks.
"David did a good job and also had a lot of fun, so now we are talking about possibilities to make a solution," he said. "Maybe there will be a positive surprise, but at this point in time I can't make any promises."
