Three-time Tour de France champion Alberto Contador yesterday went on the offensive amid fresh allegations that he received a blood transfusion during this year's race.
Reports in Belgian magazine Humo alleged that he may have used banned substance Clenbuterol during the Criterium-Dauphine race in June and withdrawn blood thereafter to use for a later transfusion.
He had dismissed earlier claims that he took performance-enhancing products and vowed to sue anyone who made similar claims.
