Michael Schumacher's manager says he knows nothing about the official comeback caps on sale in the Spa-Francorchamps paddock this weekend.

For 25 euros, punters can celebrate the seven time world champion's sensational return to F1 with the familiar red cap featuring the insignia 'Schumi', 'comeback' and '09' -- even though Schumacher, 40, called off the comeback due to injury.

"I know nothing about it," manager Willi Weber told Germany's Bild newspaper.
