Swiss magazine L'Illustre has accused controversial Kazakh rider Alexandre Vinokourov of buying his 2010 victory in the Liege-Bastogne classic race, Sports-Information agency reported today.
Sports-Information quoted L'Illustre's Wednesday edition as saying Vinokourov - who also won the race in 2005 and has four stage wins on the Tour de France but who then served a ban after testing positive for blood doping in 2007 - made a 100,000 euros ($A131,400) payment to Russian Alexandr Kolobnev.
The report alleged Vinokourov, 38, made the payment to ensure that Kolobnev did not push him to the line in a sprint finish between the pair.
Questioned by the magazine, Vinokourov, who retired in the summer having originally said he was retiring at the end of 2007, said he had simply offered his fellow rider a loan and denied wrongdoing.
"I never did that in my career - I always fought to win."
L'Illustre based its report on an exchange of emails between the two racers dating back to the day after the race.
Kolobnev is alleged to have passed on his bank account details in the Swiss city of Locarno, an account into which the payment was allegedly made.
Asked about the arrival of the cash in Kolobnev's account, Vinokourov said: "It's my private life."
He added: "It's another story to blacken my name. I often loan money left and right."
Kolobnev is currently under a doping cloud as he awaits an appeal by the International Cycling Union (UCI) to the Court of Arbitration for Sport (CAS) against the Russian federation's decision to impose a fine and a warning on the rider following a failed dope test.
