PLAYERS PAST AND PRESENT WITH THEIR OPINION ON THE GOAT SUBJECT:
"Someday we will say Federer's the best of all time" Pat Cash
"If he continues to play tennis like this, he will definitely break Pete's record. Federer can be the best ever; he has the potential. The only question is whether he has the desire." Richard Krajicek
“By far the greatest in the history of the men’s game” – John McEnroe
“He is the best player in the world…the complete tennis player” – Rod Laver
“On his day, he is the best that has picked up a racket” – Jim Courier
“Roger Federer is one of the best players of all time, there is no doubt about that…he’s an artist out there…he seems to be a throw back to the days of Laver and Rosewall…it’s a treat to see him” Bud Collins
“In my opinion he’s one of the best of the history of the game…he’s going to be the best” – Rafa Nadal
“It’s difficult to say who is the greatest tennis player in history. The people who are usually mentioned are Roger, myself and Rod Laver, and I think it’s probably one of us three” Pete Sampras
"Pete (Sampras) was great, no question…But there was a place to get to with Pete. It could be on your terms…There's no such place with Roger. I think he's the best I've played against." Andre Agassi
"...the best player ever to play the game," Andy Murray
“Federer was the best player I played against and I played Pete Sampras seven times. I played Federer 13 times and his game is so complete, there are no holes in his game that make you feel you can attack.” Tim Henman
“After this, I would say he's going to win more Grand Slams, many more, if he continues to play with the kind of passion he has now. It was an unbelievable performance against Murray and I'm now 100% convinced he will break Pete Sampras's record." Matts Wilander
"For me, watching Roger Federer is like watching an artist, because Roger can do anything on a court... Roger wants to be the player who wins the most Grand Slams, and I believe he will. If he stays motivated - and away from injuries - he's going to be the greatest player who ever lived." Bjorn Borg
“Roger continues to set new standards not just for tennis supremacy, but for all sports. He is not only one of the greatest tennis players of all-time, but one of the greatest athletes in the history of sports,” Etienne de Villiers (ATP)
"He plays offense unbelievably well. He plays defense better than anyone I've ever played. He makes so many 'gets,' and when he gets to it, he doesn't just put it back; he puts it where it's difficult for you to hit the next shot. Volleys well. Serves well. Handles the pressure of being number one in the world. He's handled the pressure of being against a crowd...He obviously puts pressure on himself to succeed, and has handled all that. Got the biggest forehand in the game. Seems to be able to create pace out of nothing. I could keep going." JAMES BLAKE
"He's probably the best I've faced. He's the most complete tennis player in the history of tennis, that's for sure, with all due respect to (Andre) Agassi and (Pete) Sampras and the rest of the gang." Safin in 2009
"The best in the history of the game" Solderling

The rest is up to us, we can have our own opinion on the matter. Its all pointless anyway, I've always believed in a top 5 or top 10 as picking just one player out of so many excellent players over so many decades is like picking one greatest film or song of all time when there are so many to choose from.
