Roger Federer said Andre Agassi's admission that he used crystal meth and then lied to the ATP about it in 1997 is disappointing, but stressed he believes tennis is a clean sport today.
"It was a shock when I heard the news," Federer said at a press conference today in comments published by AFP. "I am disappointed and I hope there are no more such cases in future."
Federer, who beat Agassi in the 2005 US Open, said Agassi's contributions far outweigh his errors in judgement.
"(Agassi) has done a lot for tennis, both as a player and as a human being," Federer said. "Today, he raises millions of dollars for his foundation for disadvantaged children."
Pointing out top players today are tested between 20 and 30 times a year, Federer said "our sport must stay clean."
