Disgraced former Tour de France winner Jan Ullrich has admitted that he underwent blood doping procedures under the guidance of a Spanish doctor at the heart of a major drugs scandal.
The 39-year-old German, who was banned for two years in 2012 for a doping offence, had previously confessed to having contact with Eufemiano Fuentes but consistently denied being illegally assisted by the doctor.
On Saturday, however, Ullrich was quoted in German weekly news magazine Focus as saying he had been helped by Fuentes.
"Yes I did undergo Fuentes treatments," the 1997 Tour de France champion said. "Almost everyone took performance-enhancing substances back then.
"I did not take anything that the others did not take. Cheating starts for me when I gain an advantage. That was not the case. I wanted to have equal chances."
Ullrich added that he used his own blood for the treatment.
Fuentes, at the centre of a much-publicised trial in Spain earlier this year, had told the court that as well as cyclists, his clients included soccer players, athletes, tennis players and boxers.
The Operation Puerto scandal broke in 2006, when Spanish police launched raids that uncovered more than 200 code-named blood bags, some of which were linked to cyclists.
Ullrich, who retired in 2007 after also winning gold and silver medals at the Sydney 2000 Olympics, remains the only German to win the Tour de France.
In February 2012, Ullrich was found guilty of a doping offence by the Court of Arbitration for Sport (CAS) and retroactively banned for two years from Aug. 22, 2011.
In addition to the ban, all results after May 2005 were removed from his list of achievements.
