Michael Schumacher is being aided in his recovery by mysterious "positive energy," according to his manager, Sabine Kehm.

Kehm said she believed energy was being generated by fans of the F1 racing legend, adding that the positive vibes have also helped the stricken star's family care for him.

"I believe that positive energy does them good," Kehm told The Local, as she praised well-wishers for supporting the family during the struggle.

"I can only say again that the family is very happy and touched by the sympathetic messages" she said. "We appreciate the condolences from around the world."

But Kehm warned that Schumacher faces a "difficult and long" recovery from devastating head injuries.

Kehm said: "Michael is making progress appropriate to the severity of his situation, but it will be a difficult and long process."

Her words follow news last week that the seven-time world champion is currently paralysed in a wheelchair and unable to speak.

Schumacher suffered catastrophic head injuries by cracking his head on a rock in a ski crash last year in the French Alpine resort of Meribel.
