Willi Weber helped Schumacher break into F1 and remained his manager until shortly before the German’s first retirement from the sport in 2006. He also looked after a number of other drivers, including Ralf Schumacher and more recently Nico Hulkenberg.
He has now launched an attack on the current crop of F1 racers, singling out their tendency to complain about rivals over the radio. This, says Weber, means they do not stack up against past greats.
"Who wants to see the wimps of today crying on the radio?" Weber said in an interview with Sport Bild.
Weber also hit out at F1 supremo Bernie Ecclestone, blaming him for the supposed drop off in F1’s popularity.
"There are many reasons for the decline of the Formula One," said Weber. "First, the fish rots at the head. Bernie Ecclestone is much too old to embrace the age of new media while FIA president Jean Todt lacks the power to enforce.
“These men think only of their own interests,” he added.
Weber’s last major F1 role was with Hulkenberg, who he managed until 2011.
