Former F1 star Michael Schumacher's has shown "moments of consciousness and awakening", more than three months after suffering serious head injuries in a skiing accident, according to his manager.

Manager Sabine Kehm said in a statement that "Michael is making progress on his way" before adding that "we keep remaining confident".

Schumacher, 45, slammed his head on a rock while skiing off-piste in the French Alps resort of Meribel last December. The most successful Formula 1 champion of all time has been in a stable but critical condition since then in a hospital in the eastern French city of Grenoble.

Doctors started lowering the retired German racing driver's sedation at the end of January to wake him up from an artificial coma.

Schumacher, who won a record 91 Grand Prix victories, left the sport last year after a disappointing three-year comeback with Mercedes following an earlier retirement from Ferrari at the end of 2006.
