London, Nov 1 Eight time Grand Slam winner and one of the finest tennis players, Andre Agassi's revelation that his father Mike Agassi asked him to take the drug speed before a tournament and that he took it, has angered the World Anti-Doping Agency.

Agassi may face Wada 'perjury wrath' over claims of taking speed. The WADA asked tennis bodies to investigate the possibility of a erjury case against the tennis player The tennis golden boy said that his father used to give him drugs to take before matches, including pills that were high in caffeine, and possibly even the illegal amphetamine speed, The Telegraph reports.

The suggestion that Agassi may have taken the drug, which has not been made public in this country until now, will further damage his image after his disclosure last week that he took crystal Methamphetamine, possession of which carries a maximum five-year jail sentence in the US.

The American tennis legend revealed his use of the substance in his new autobiography "Open" and that he received a call from a doctor working for the ATP in the autumn of 1997 to inform him that he had failed a drug test.

David Howman, the director general of Wada, said he would be writing to the tennis authorities to ask them to investigate "the possibility of perjury" or "a breach of the law" following Agassi's admission that he explained his positive test result for crystal meth in 1997, the paper reports.

Though WADA has an eight-year statute of limitations, and it is highly unlikely that they could punish the former Wimbledon hampion, Howman indicated that he did not consider this to be a dead issue, and hoped that the ATP and the International Tennis ederation would act responsibly. (ANI)
