Michael Schumacher's former manager and friend Willi Weber believes the Formula One racer's family are "not telling the whole truth" about his condition following a ski accident in the French Alps in 2013.
The 47-year-old was placed into a medically-induced coma after the crash, which saw him bang his head on a rock but there has been little about his condition since he came out of the coma since months later.

Speaking to German magazine Bunte, Weber said: "For some time now, I've been saying that the Schumacher family is not telling the whole truth.
"It's time to pour pure wine for his millions of fans. But I'm biting on granite because for a long time my advice is no longer heard.
"When I'm home alone and the phone rings I often feel that it will be Michael saying 'Willi, how's it going?'
"Hope dies last."
In May 2015, Schumacher's manager Sabine Kehm told German newspaper BILD: "We are pleased to continue to say that he is making progress, and I say that always, given the severity of his head injuries."
