- "Oh, I would be honoured to even be compared to Roger. He is such an unbelievable talent, and is capable of anything. Roger could be the greatest tennis player of all time." - Rod Laver, winner of 11 Grand Slams, considered by some the greatest player to ever play the game of tennis.
- "I think he can dominate tennis for as long as I did...We have the same temperament and like me, he makes playing look easy...He can do just about anything he wants with a racquet and he dominates everybody as I did several years before." - Pete Sampras, winner of record 14 Grand Slams. Federer beat Sampras in their only meeting - at Wimbledon in 2001.
- "He's the most gifted player that I've ever seen in my life. I've seen a lot of people play. I've seen the (Rod) Lavers, I played against some of the great players - the Samprases, Beckers, Connors', Borgs, you name it. This guy could be the greatest of all time. That, to me, says it all." - John McEnroe, winner of 7 Grand Slams.
- "Roger Federer is the only guy I watch for his strokes. He is just beautiful. He can hit every single shot you could ever think of. John [McEnroe] and Ilie [Nastase] were very talented but you always knew there were some shots they couldn't hit. Not with Federer. I would go and watch him practise, he's so good." - Ivan Lendl, winner of 8 Grand Slams.
