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

โ€œI get news about him constantly, and unfortunately it's not good,โ€ Montezemolo said on Thursday.

โ€œHe 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.โ€

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.
