MELBOURNE (AP) - Novak Djokovic has heavily criticised Lance Armstrong's long-expected doping admissions, saying the seven-time Tour de France winner is a disgrace to cycling and "should suffer for his lies".
At the same time, the No. 1-ranked man in tennis says the drug testing program in his sport is "good" but concedes he has not had a blood test in six months.
Djokovic advanced to the fourth round at the Australian Open on Friday with a straight-sets win over Radek Stepanek, but most of his post-match news conference was devoted to comment on Armstrong's admissions in a US television interview with Oprah Winfrey.
Djokovic said: "I think it's a disgrace for the sport to have an athlete like this."
