Michael Schumacher’s manager has warned against reports on the F1 legends health which come from unofficial sources. Sabine Kehm said in a statement that reports on his condition “not coming from doctors treating him or from his management must be treated as invalid and pure speculation.”

The announcement comes following Phillipe Streiff, Schumacher’s friend and former F1 driver, telling reporters on Friday that Schumacher’s life was no longer in danger.

Schumacher remains in a “critical but stable” condition in hospital in Grenoble following last weekend’s skiing accident.

The statement read: "Michael's condition remains critical but stable. We would like to clearly stress that any information regarding Michael's health not coming from the doctors treating him or from his management must be treated as invalid and pure speculation."
