Novak Djokovic clueless over anti-doping procedures: WADA

World Anti-Doping Agency (WADA) president John Fahey has said that he does not think Serbian tennis player Novak Djokovic has the faintest idea what his organization does.

According to CNN, the former World No.1 recently said he had lost faith in the system and the Serbian labeled compatriot Viktor Troicki's 12-month ban from tennis for missing a drugs test a total injustice, saying he was now nervous to give any sort of sample.

However, Fahey dismissed the six-time grand slam winner's comments as unhelpful and said it was up to the sport to do more to fight against doping, according to the report.

He also said that the Lance Armstrong case shows that nobody is above the regulations.
