Former Formula One driver Philippe Streiff told the French daily on Sunday
that the German seven-time racing champion was "communicating with this eyes" and that while he's recognizing his family again, he still has "big problems with his memory."
He added that physically, Schumacher was working on sitting up on his own.
Streiff cited his friendship with Schumacher's doctor, Gérard Saillant as the source of this information. He also said he had contact with Corinna Schumacher, Michael's wife of nearly 20 years.
"The statements of Philippe Streiff can only make me wonder. He definitely does not have contact with Professor Saillant and definitely not with Corinna."
Streiff also called Schumacher "my friend", saying that he worked with the Schumachers in 2010 when they founded the Brain and Spine Institute in Paris (ICM), where he also works.
Furthermore, Streiff lives in Grenoble, where Schumacher was first hospitalised after a freak skiing accident put him into a six-month-long coma.
"I was there," Streiff told Le Parisien.
This only provoked further ire for Schumacher's spokesperson.
"There is absolutely no contact with the Schumacher family. There has never been a friendship between Mr Streiff and Michael," Kehm said.
It's been one year since the German Formula One ace suffered severe head injuries while skiing with this family in the French Alps.
After being in a coma for half a year, Schumacher is "making progress appropriate to the severity of his situation, but it will be a difficult and long process," Kehm said in November in an interview with broadcaster RTL.
Schumi, as he is known in Germany, has been recovering in his home in Gland, Switzerland.
His family say they were "confident and hoping for the best" for his recovery.
