Germany's Erik Zabel, who in May admitted he used the banned substance erythropoietin (EPO) in 1996, said he was willing to give back the green jersey he won as the Tour de France's best sprinter that year.

Zabel told the Bild am Sonntag newspaper that he could understand calls from Tour organisers for him to return the jersey, which is hanging on a wall at his home.

'I was expecting that because Bjarne Riis's Tour victory that year was erased after his confession,' Zabel said.

Riis admitted in May to doping and said he could give back his yellow jersey which is in a box in the garage.

'But I won't have to dig it out of the garage,' Zabel said. 'If they want it, my wife Cordula can bring it to Paris.'

Zabel, who won the green jersey six times, was wearing the green jersey in this year's race until handing it over to Belgian Tom Boonen on Friday.
