“It is not so surprising that Andre Agassi used drugs during the early, heady days of his sporting stardom. What is surprising is that Agassi chose to admit his abuse.” Peter Lalor, The Australian

“The deceit freely admitted by one of the superstars of the game will sit uneasily with the tennis powerbrokers and the global sporting bureaucracy. Agassi may have blamed his drug taking on worry about his relationship at the time with the actress Brooke Shields, but the revelation of Agassi’s pretence is explosive.”Jacquelin Magnay, The Age, Melbourne

“This is Agassi’s mea culpa and he set out to write the most revealing, literate and toes-stompingly honest sports autobiography in history. It is the story of a flawed man who sees everybody's imperfections, but none more than his own.” Rick Reilly, veteran American sports writer, on ESPN.com

“The first excerpts have been released and, wow, are they explosive. Not only does Agassi admit to using crystal meth, but he describes how he evaded drug testers by lying about his usage.” Busted Racquet blog on Yahoo! Sports website

“Would he have got away with it if he had been a cyclist? As this happened in 1997 the answer is probably yes, given that the year before self-confessed EPO-powered Bjarne Riis won the Tour de France. But Agassi’s admission puts him in an unpleasant place, among a group of top sportsmen whose records have fallen under the doping shadow. Who’s next?” East Anglian Daily Times

“The claim of dishonesty, coupled with the fact he was never banned, suggests the ATP took his defence at face value and brushed his case under the carpet. After this high-profile revelation, more suspicion hangs over tennis than ever before. How many more cases like this have there been?” Jonathan Overend, BBC News

“In terms of Agassi’s reputation, I don’t think the fact he took drugs and lied back in 1997 to the ATP will hurt him one bit — the Agassi the whole world grew to love this century, at the end of his career, was unrecognisable compared to the wild-child Agassi who first burst on to the scene. This will be seen as part of his disreputable past, from which he has long since moved on.”“Eddie George” on BBC Online

“This is not courage. If Agassi is so honest and courageous he would have come out then and there, admit to his hard drug use, face the consequences and go on. This is like robbing a bank, then writing about it later from Brazil.” Eric M on Times Online

“His stupid drug act disgraced himself. The illegal use of drugs, especially such a dangerous one as Meth, can screw you up and even kill you. He was old enough to know better.” Jack on CNN tennis blog
