Michael Schumacher has made "progress" since leaving hospital and rehabilitation and returning to his home in Switzerland.
That was the cautious news on Thursday of Jean-Francois Payen, one of the original team of doctors who worked on the then critically-injured seven time world champion in Grenoble after his skiing accident.
Dr Payen told French radio RTL that he has made a visit to see German F1 legend Schumacher in recent days, following his return home to be with his family.
"I kept seeing him, first at Lausanne, and now at home. It's to see how he progresses and tell his wife and children what changes I observed," he said.
"I have noted some progress but I would say we should give him time," Payen revealed.
When asked how long Schumacher's recovery might take from now, Payen answered: "It's like for other patients, we are on a timescale which goes from one year to three years and we need to be patient.
"Anyway, he is in the best environment, (with) his family, his wife is surrounded by excellent advice and has implemented all it takes for it to move forward," he added.
