The incident left him in a coma for six months with his family tight-lipped on his progress, releasing limited information on the health of the 47-year-old.

Ross Brawn, the former technical director at Ferrari under whom all of Schumacher’s 91 race wins and seven titles came, said his friend’s health was slowly improving.

“The family have chosen to conduct Michael’s convalescence in private and I must respect that,” Brawn told BBC Sport. 

“There are encouraging signs and we are all praying every day that we see more of them. So it is difficult for me to say very much and respect the family’s privacy.

“Most of it (the information released) is wrong and we just pray and hope every day that we continue to see some progress and that one day we can see Michael out and about and recovered from his terrible injuries.”

Schumacher’s family took a German tabloid to court earlier this year after publishing a stating the seven-time world champion had regained the ability to walk.
