Michael Schumacher's former team boss says the seven-time world champion's return to Formula One at the age of 41 has been a huge personal error.
Eddie Jordan first handed the German his chance in Formula One, signing him up as a driver for his Jordan team in 1991 when Schumacher was 19.
But Jordan's told a German newspaper that while Schumacher's return has been good for the sport it's been a huge error for him.
He says a comeback at 41 against young men 20 years younger is simply against the laws of physics and medicine.
Schumacher finished ninth at the British Grand Prix at Silverstone and is ninth so far this season with 36 points from 10 races, 100 behind the leader Lewis Hamilton.
