Victor Conte, the former doping guru, has claimed that all eight 100 meter finalists at the Sydney Olympics were cheats.

The finger of suspicion was also raised by Conte at world and Olympic champion Usain Bolt of Jamaica in an interview with Italy’s La Gazetta dello Sport.

“I believe that before the BALCO affair, 80 per cent of athletes were using steroids, today that figure stands at about 65 per cent,” Conte said in the hard-hitting interview.
