Ex-Ferrari boss Luca de Montezemolo has confirmed that the outlook for seven-time Formula One champion Michael Schumacher is not good.

“I get news about him constantly, and unfortunately it's not good,” Montezemolo said on Thursday.

“He was the most successful driver Ferrari ever had. He only suffered one accident in his entire career, in 1999, and it was our fault, not his. Unfortunately, a skiing accident ruined his life.”

Schumacher suffered a skiing accident in December of 2013, suffering life threatening injuries.

He remained in hospital in a coma for some time, before he was discharged in September 2014 to continue his recovery at home.
