Serbian tennis superstar Novak Djokovic has said that he has lost faith in the sport of tennis' anti-doping programme, adding that it does not work.
According to USA Today, the second-ranked Serb ripped the process that saw his childhood friend and fellow Serb Viktor Troicki's ban partially upheld by the Court of Arbitration of Sport.
The decision, announced Tuesday, reduced Troicki's suspension for skipping a blood test at the Monte Carlo Masters in April from 18 months to 12 months, the report said.
Djokovic said that it was not just bad news for him, it also proved again that this system of WADA and anti-doping agency does not work, referring to the World Anti-Doping Agency and its code, which has been adopted by tennis.
Due to the ban, Troicki, 27, who once ranked as high as No. 12 in the world, cannot participate in Serbia's Davis Cup final against the Czech Republic later this month and will not be able to return to competition until July 2014, the report further said.
Djokovic also called the tribunal system a 'total injustice' and the anti-doping process, which is overseen in tennis by the International Tennis Federation, 'ridiculous,' according to the report.
He later called the CAS tribunal procedure a sham, the report mentioned.
