Michael Schumacher making 'progress': Manager

Berlin: Seven-time Formula One world champion Michael Schumacher continues to make progress in recovering from a severe head injury, nearly a year-and-half after a skiing accident, according to his manager.

"We`re glad to be able to continue to say that he is making progress, as I always say, given the severity of his head injuries," said his manager Sabine Kehm at a sponsor`s event.

But Kehm also reiterated 46-year-old Schumacher`s recovery will be a lengthy process following the accident in the French Alps in December 2013 which left him in a coma in Grenoble hospital for 189 days.

Last June, Kehm announced Schumacher was out of a coma.

Schumacher has been treated at his Swiss home near Lake Geneva since September last year and has yet to make a public appearance since the accident.
