Ralf Schumacher is refusing to rule out a return to formula one, but he admits his chances are very remote.
The former winner of six grands prix dropped off the grid last season, at the end of a disappointing three-season tenure with Toyota.
He now races with Mercedes-Benz in the German touring car series DTM, but said he is open to offers to return to the pinnacle of motor racing.
"If there is something sensible (offered), I would certainly think about it," the 33-year-old told the German broadcaster Premiere.
Schumacher acknowledges, however, that expecting to resurrect his formula one career is "not realistic", given his "extremely bad" final season in 2007.
