Michael Schumacher's manager Sabine Kehm has confirmed that the condition of the stricken Formula 1 legend has "not changed".
The 45-year-old has been in a medically-induced coma in Grenoble University Hospital since suffering head injuries in a skiing accident on December 29.
The seven-time champion hit his head on a rock while skiing off-piste in the French Alps.
While there have been reports regarding the sportsman's condition, Schumacher's representative has stated that he remains in the waking-up process.
A statement read: "Michael is still in the wake up phase. The situation has not changed. Any medical information published which is not confirmed by the team of doctors treating Michael or his management has to be considered as not valid."
Schumacher has undergone two operations on his brain since being admitted to hospital.
