Michael Schumacher showing positive signs

The seven-times Formula One world champion is now approaching 100 days in a coma at the University of Grenoble hospital since sustaining severe head injuries in a skiing accident at the end of December.

The latest update from Schumacher's manager Sabine Kehm - and the first for just over three weeks - again offers hope the 45-year-old will somehow make a miracle recovery.

"Michael is making progress. He shows moments of consciousness and awakening," said Kehm.

"We are on his side during his long and difficult fight, together with the team at the hospital in Grenoble, and we remain confident."

Not for the first time Kehm has thanked Schumacher's fans, and all the well-wishers around the world, for their continuous support.

Naturally, as time has progressed and Schumacher has failed to emerge from his coma, there has been growing speculation as to whether he will survive, and if he does, the nature of his condition.

Kehm, however, is unwilling to go into specifics with regard to Schumacher's situation and his care, adding: "We would like to thank you all for the continuous sympathies.

"At the same time we again ask for your understanding that we do not intend to disclose details.

"This is necessary to protect the privacy of Michael and his family, and to enable the medical team to work in full calmness."

Recent speculation has centred around the fact Schumacher's wife Corinna was considering moving her husband to their home for him to continue his treatment by building a specialised medical suite.

However, it is understood that is not part of the family's plans as they believe he is receiving the best treatment possible at the hospital.

Schumacher was placed in an induced coma after undergoing two separate operations to remove blood clots from his brain following his accident on December 29.
