Seven times Formula One world champion Michael Schumacher, who came out of retirement last year, has lost the "edge" that had separated him from the rest at his peak, according to his rival since karting days and fellow-German Heinz-Harald Frentzen.


Here to attend the unveiling of drivers for the inaugural i1Super Series, the 44-year-old Frentzen who was once considered to be quicker than Schumacher, said: "As you grow older, you tend to hesitate and become indecisive whether or not to push and take risks.

You lose precious tenths of a second. I think, Michael is at that stage in his career," said Frentzen, whose rivalry with Schumacher dates back to the Mercedes Junior programme. He opted out of it in favour of Jordan team in F3000 series. Schumacher earned a spot in the Jordan F1 team the same year and never looked back.
