Pressure mounts on Andre Agassi

Former Number One-ranked, Marat Safin believes that Andre Agassi should give his tennis titles back after confessing he tested positive for a banned substance during his career and lied about it to the ATP.



Agassi admitted in his book \"Open\" that he used crystal meth in 1997 and failed a drug test, a result he said was thrown out after he lied by saying he \"unwittingly\" took the substance.



Safin, who will retire this month, said in an interview with L\'Equipe newspaper that Agassi should \"give his titles, his money and his Grand Slam titles\" back.



Agassi, who retired in 2006, won 60 titles, including eight Grand Slams, during his career. He recently told The Associated Press that he had to speak about his lies because he couldn\'t live with it anymore.
