Former French Open champion Carlos Moya has said in an interview to Tennisworld.es that Roger Federer is the closest anyone can get to tennis perfection. When asked if there was perfection in tennism this was is his answer: "Everything can be improved.
If we talk of perfection, the one that comes very close and Federer. In 2004 and 2005 he was unbeatable. Djokovic seems to have taken the same road, but for me, perfection is not just about winning matches, but as you win, how do the shots and the way that you move on the field.
I think if we consider these aspects perfection is Federer. it's hard to make comparisons, especially for me that I have not seen Rod Laver or other players of his generation, but I've seen Federer play and is definitely the person who comes closest to being perfect."
