Seven-time world champion Michael Schumacher's return to Formula One at the age of 41 was a "huge personal error", according to his former boss Eddie Jordan.

It was Jordan who 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 years old.

But Jordan said his return to a young man's sport was a miscalculation.

"Michael Schumacher's return was an excellent thing for the discipline, but for him personally, it's a huge error," Jordan told Sport Bild.

"To make a comeback at 41 years of age, to pitch yourself against young men 20 years younger than you, is simply against the laws of physics and medicine."

Jordan added Schumacher had nothing to gain.

"Except for maybe feeling good, but even that, that's not the case. Do you think that it would please him to be beaten by (Mercedes team-mate) Nico Rosberg?," Jordan said.

Schumacher finished ninth at the British Grand Prix at Silverstone on Sunday, with Rosberg in second.

In the overall standings, Schumacher sits in ninth spot with 36 points from 10 races, more than 50 points off Rosberg and 100 off table-topper Lewis Hamilton.

HOLD ON. Just not too long ago, Eddie Jordan was singing a totally different tune, saying "Schumacher will have a huge impact"
