F1 great Michael Schumacher's former boss at Ferrari has said the latest news about the German's health "is not good" but has refused to elaborate.


"I have news and unfortunately it is not good," Luca di Montezemolo told reporters on Thursday.


When contacted by BBC Sport, Schumacher's official spokesperson Sabine Kehm declined to comment.


Seven-time world champion Schumacher, 47, suffered severe head injuries in a skiing accident in December 2013.
