Nick Fry, who worked alongside Schumacher for three years at Mercedes, believes the sporadic offerings about a driver who won a record seven world championships, 91 grands prix, and commanded a following of millions around the world, are not enough.
“Corinna and the family have kept a very tight control on information about his treatment which, I think, is a pity,” Fry wrote in his book Survive, Drive, Win Seen by PA News Agency.
“There are millions of people out there who have a genuine affection for Michael, and that’s not just his fans in Germany or fans of Mercedes Benz.
“Because of what he achieved, people would like to know about his condition; they are inquisitive and they genuinely feel for him.
“I do think that reporting on how he is, regardless of whether it is good or bad news – and possibly it is bad news – is important because people can empathise with him.”
Fry was chief executive for Mercedes during Schumacher’s largely unsuccessful second spell in Formula One.
He was replaced at Mercedes by Toto Wolff in 2013.
