World No. 1 Novak Djokovic weighs in on famous cyclist Lance Armstrong’s confession that he used performance-enhancing drugs during his career.

“It would be ridiculous for him to decline and refuse all the charges because it has been proven,” Djokovic said at the Australian Open. “They have like a thousand proofs that he’s positive. I think it’s a disgrace for the sport to have an athlete like this. He cheated the sport. He cheated many people around the world with his career, with his life story. I think they should take all his titles away because it’s not fair towards any sportsman, any athlete. It’s just not the way to be successful. So I think he should suffer for his lies all these years.”  
Djokovic added that he is comfortable that drug testing in tennis is rigorous enough.  
“It’s really good,” he said. “Anti-doping regulations a little bit maybe more strict in sense that you have to fill the whereabouts documents and you have to basically give an hour or two in every day of your life in a whole year, where you are. But on the other hand, it gives them an opportunity to test you. And you know it is the same for the other players. At least from that point of view it’s fair. And I have nothing against the anti-doping federation, association, testing me 10, 20, 30 times a year.”
