Mystery surrounds the condition of the seven-time F1 champion who suffered severe head injuries after crashing while skiing in the Alps.
Schumacher, 45, is being cared for at his family home near Lake Geneva in Switzerland where he continues to recover from the horror accident in December 2013.
Last week it emerged the German cannot walk after his family sued a newspaper for making false claims.
But three years on from the tragedy, his former Ferrari teammate, Gerhard Berger, still believes the F1 legend could bounce back.

Speaking to German newspaper Koelner Express, he said: “I believe in the miracle and very much hope that we will soon hear positive news from Michael.”
The Austrian, who is the DTM series boss, is still in contact with Schumacher’s wife Corinna and son Mick, the paper reported.
The former Ferrari and McLaren driver said: “How Corinna and Mick deal with this difficult situation is admirable.
“I think it’s a wonderful story that Mick has listened to his heart and wants to take on the racing profession.”
“I believe in the miracle and very much hope that we will soon hear positive news from Michael.”
Mick – whose nickname is Quick Mick – is competing in Formula Three this season and has ambitions to follow in his dad’s footsteps.
Berger added: “Of course Michael’s footprints are enormous, but Mick has the talent and the right environment to deal with the pressure.
“He is a Schumacher and he knows what he’s doing.”

His comments come after ex-F1 star Philippe Streiff told Daily Star Online Schumacher will “probably not 100% recover” from his “neurological” injuries.
Speaking exclusively to Daily Star Online, ex-F1 star Streiff, 65, said he fears it may be “difficult” for Schumacher to ever walk again.
He claims: “After a neurological accident, you always have hopes.
“But after more than three years, it’s probably more difficult.”
