Michael Schumacher's former team-mate Felipe Massa has claimed that the German "gave reactions with his mouth" during a recent secret visit.

Massa, who will drive with Williams this season, went to see Schumacher at the Grenoble hospital where he has been in a coma since a December ski accident.

Massa said: "He looks normal, and he also gave some reactions with the mouth and everything. So it’s positive to look at him. I have no experience to say anything. I’m not a doctor. But when I saw him, for me, it looked very positive."

Schumacher has been in a medically-induced coma for almost two months, although his spokesperson Sabine Kehm confirmed he was in the "waking up process".
