Rafael Nadal and Roger Federer both say they're shocked by the news that tennis authorities covered up Andre Agassi's use of banned drugs.
Multiple Grand Slam winner Agassi said he lied about using crystal meth to the ATP in 1997 to avoid a ban.
Nadal says if the ATP covered for Agassi then he thinks that's dreadful.... Federer added he's disappointed and he hopes there are no more cases in future.
World number two Nadal, who played Agassi twice in his career, says the ATP's decision to take the American on his word without further investigation was a slight on his fellow tennis players.
Agassi, who won eight Grand Slams and is one of only six men to win all four major titles, said in his autobiography this week that he took the highly addictive drug with a former assistant and then lied to the ATP that his drink had been accidently spiked.
The ATP believed his story and took no action against the Las Vegan who at the time had slumped to 141 in the world rankings despite having three Grand Slam titles already under his belt.
While world number one Roger Federer was equally surprised, he admitted that Agassi, now 39, "has done a lot for tennis, both as a player and as a human being".
And former US Open winner Andy Roddick insists his impression of Agassi will not be clouded by the drug use... saying he will always be his idol.
The World Anti-Doping Agency (Wada), who have since helped tighten up drugs procedures in tennis, are awaiting a response from the ATP who they have asked to "shed light" on the case.
