Michael Schumacher's manager has said the seven-time champion is fit enough to race in F1 again, stoking speculation that he will race for Mercedes next season.
Willi Weber told the German press that Schumacher is now "absolutely fit".
"His neck is also completely fine, just like his entire psyche," Weber said. "He could drive for victories."
However, triple champion Niki Lauda played down the liklihood of a Schumacher comeback.
"I don't believe that there is one single grain of truth in them, at least from all the signals that I get," said Lauda.
