Brain experts have said it is unlikely that Michael Schumacher will make a full recovery after a ski accident in France which left him in a coma.
The 45-year-old's agent, Sabine Kehm, said in an email that "Michael is still in the wake-up phase" and "this phase can be long."
According to the Daily Telegraph, Dr Tipu Aziz, professor of neurosurgery at Oxford University, who is not connected to the racing driver's care said: "It does not bode well. The fact that he hasn't woken up implies that the injury has been extremely severe and that a full recovery is improbable."
Anthony Strong, an emeritus chair in neurosurgery at King's College London, told the Daily Mail: "The longer someone is in a coma, the worse their recovery tends to be."
Last week, Formula One racing driver Felipe Massa said Schumacher's mouth 'moved' when he visited him in hospital.
Massa said: "He looks normal, and he also gave some reactions with the mouth and everything. So it's positive to look at him."
His family has said: "We all know: he is a fighter and will not give up!"
