"The best way to beat him would be to hit him over the head with a racquet. Roger could win the Grand Slam if he keeps playing the way he is and, if he does that, it will equate to the two Grand Slams that I won because standards are much higher these days."

"Roger's got too many shots, too much talent in one body. It's hardly fair that one person can do all this—his backhands, his forehands, volleys, serving, his court position. The way he moves around the court, you feel like he's barely touching the ground. That's the sign of a great champion."

"Oh, I would be honoured to even be compared to Roger. He has such an unbelievable talent, and is capable of anything. Roger could be the greatest tennis player of all time."

"I really consider myself top 5 player in the world, which doesn't mean that I am close to Roger."

"I don't see anyone with a big enough weapon to hurt him. They're just staying back and Roger is able to dictate well enough. You just have to serve well and attack him."

"Well, I think when I look at Roger, I mean, I'm a fan. I mean, I'm a fan of how he plays, what he's about, just the fact that I think he's a class—I don't know him personally, but seems like he's a class guy on and off the court. He's fun to watch. Just his athletic ability, what he's able to do on the run. I think he can and will break every tennis record out there."

"Yes, I really hit with him when he was 15, during a tournament in Basel, and I knew then he would be good, but not this good. If he stays healthy, it will actually be a miracle if he doesn't win more Grand Slams than Pete [Sampras]. The way he picks his shots is unbelievable. He is fast, he has a great volley, a great serve, great backhand, great everything. If I was his coach, what can I tell him? He is a magician with a racket. Even when he is playing badly, which is rarely, he can still do things with his racket nobody else can do."

"Federer is the best player in history, no other player has ever had such quality."

"Roger is just the greatest player of all time. He is the most beautiful player I’ve ever seen and I don’t ever get tired of watching him. Rod Laver is my idol, Pete Sampras is the greatest grass court player ever, but Roger is just the greatest player of all. I think we can all appreciate how incredible he is even more lately, because he’s shown a bit more emotion on court and he’s become a father so he seems a bit more human, more relatable. That makes what he’s doing seem even more amazing."

"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."

"In my opinion he's the best player ever. When you play tennis, playing Federer is kind of a dream because you can see he does everything you would love to do on the court."

"If he is playing very good, I have to play unbelievable. If not, it’s impossible, especially if he’s playing with good confidence. When he’s 100 percent, he’s playing in another league. It’s impossible to stop him. I fight. I fight. I fight. Nothing to say. Just congratulate him."

"Maybe, hopefully, one day you can tell me how it feels to win Montreal."

"The metaphysical explanation is that Roger Federer is one of those rare, preternatural athletes who appear to be exempt, at least in part, from certain physical laws."

"I never can beat Roger, he’s too much for me… but the Senior Tour, I will beat him then! He’s the best of history and I’m very lucky to play the best player of the world."

"No way I would be a journalist. You guys have tried to kill Roger - often. But he's always come back and proved you wrong. So one thing I would not do is make the mistake of saying Roger is dead."

"I can cry like Roger, it's just a shame I can't play like him."

"Just about everything he does is pretty impressive. So, yeah, 50 titles at any age is impressive. 50 titles at 26 is incredible. 50 titles with 11 of them being Grand Slams, and I think now 14 being Masters Series, that's just phenomenal."

"Because he can cover so well to the forehand, it really allows him to stay at home in the backhand corner. That backhand corner gets smaller and smaller, sort of dares you to hit the forehand. There's a lot of times you do, and you're thinking that it's a good idea, then a second later you're going, 'Why did I do that?'"

"He hits shots that other guys don’t hit. You want to go over and give him a high five sometimes, but you can’t do that. You want to beat him but he’s fun to watch, too."

"What do you want me to do?"

"[...] I have a great deal of respect and admiration for the youth climate movement, and I am grateful to young climate activists for pushing us all to examine our behaviours and act on innovative solutions. We owe it to them and ourselves to listen. I appreciate reminders of my responsibility [...] and I’m committed to using this privileged position to dialogue on important issues with my sponsors."

"We need a clown for this circus."

"You gotta be careful about how you phrase that. You don't want to be rude to the other players, because you gotta face them; I don't have to face them. Yeah, I don't ask them stupid questions like that (laughing)...Um, I think there a lot of good players on the tour."

"Today, I'm totally zen."

"People sometimes miss it and sometimes they don't have it and they want it, and when they have it, they don't want it"

"Previously I always thought it was just tactical and technique, but every match has become almost mental and physical—I try to push myself to move well. I try to push myself not to get upset and stay positive, and that's what my biggest improvement is over all those years. Under pressure I can see things very clear."

"All four of those are on grass, whereas I have to play some on a hard court!"

"It's just unreal, I'm shocked myself. I've played good matches here, but never really almost destroyed somebody."

"It was just one of those days for him to forget and me to remember."

"I would so like to be Lenny Kravitz."

"I never waited 27 years, because 27 years ago I was just born. My parents never told me, 'If you don't win Roland Garros we take you to the orphanage.'"

"No no no, too late! Stop! Yeah, come on… I was allowed to challenge for like two seconds, the guy takes like ten… Every time! I can't allowed that stuff to happen! You have any rules in there or what ?! Stop showing me your hand, ok?! Don't tell me to be quite, ok?! When I wanna talk, I talk, all right?! I don't give a shit what he said, I just say he's waiting way too long…"

"Sometimes you're just happy playing. Some people, some media, unfortunately, don't understand that it's okay just to play tennis and enjoy it. They always think you have to win everything, it always needs to be a success story, and if it's not, obviously, what is the point? Maybe you have to go back and think, Why have I started playing tennis? Because I just like it. It's actually sort of a dream hobby that became somewhat of a job. Some people just don't get that, ever."

"I think you need inspiration, motivation from different angles to keep you going, because it isn’t that simple just to wake up every morning and go for another travel around the world, another practice, all these other things; another fitness workout, another stretch. It’s always nice, but you need to have some success and you need to have the right reasons why you’re doing it. I think I’ve always been able to do that and I really enjoy myself out on the court."

"I had a taste of what the best is tonight and I think Roger has that extra gear. He has good volleys and he has this little backhand flick that honestly, I have never seen before... it’s something that I didn’t have. I am happy with my performance tonight. I hung in there right until the end."

"For me, in my prime, I felt unbeatable. In Roger's days, he's unbeatable. It's really hard to put one guy over the other. Having said that, I think Roger is dominating the game much more than I ever did. I think he's going to go on and pass 14 and win 16, 17, 18 majors. I think he's going to break all records."

"You guys are brutal. Absolutely brutal. The guy has only made two Grand Slam finals this year. I would love his bad year. I would love it."

"Roger Federer will undoubtedly become the greatest tennis player to have graced the sport if he wins the French Open. It ends the discussion of where he fits in the history of the game. If it wasn't for [four-time champion Rafael] Nadal, he probably would have won a handful of these things. So nobody would underestimate where he deserves to fit in this game. He's extraordinarily talented and talk about grace on court; watching him play is something special to see and if he does it tomorrow, he'll know what an accomplishment it was."

"I never played anyone playing that fast. He doesn’t have any weaknesses at all. He really deserves to be called the best player of all time."

"His win today at the French Open, tying Pete Sampras’s record for major titles and the completion of a career grand slam firmly places him in a special place as the greatest player of all time. He has earned his place and he has proven he belongs. Roger is a champion for the ages."

"What he’s done over the past five years has never, ever been done — and probably will never, ever happen again. Regardless if he won there or not, he goes down as the greatest ever. This just confirms it. Now that he has won in Paris, I think it just more solidifies his place in history as the greatest player that played the game, in my opinion. I’m a huge Laver fan, and he had a few years in there where he didn’t have an opportunity to win majors. But you can’t compare the eras. And in this era, the competition is much more fierce than Rod’s."

"It’s a combination of how many grand slams have you won, how many tournaments have you won, how many years you were number one, and he’s got all those combinations. The body of work is phenomenal and now he has got that French Open and I think he can just go on and sip Margaritas for the rest of his life."

"No, the other one was a night session too and I was wearing a white! No I'm not superstitious at all as you can see and… I try not to be… and because I try no to be, I guess I am… So it's really strange!"

"For me Roger is the greatest player ever who played the tennis game. It’s always good to see him play and win and we are going to see so much more of Federer in the future; he is going to win more grand slam tournaments."

"We are witnessing history. This is the most dominant athlete on planet earth today."

"[Federer] ...is the most beautiful man to watch play tennis. The most beautiful I've ever seen play. His movement, combined with the artistry, his racquet, the look, he's got everything going."

"Roger can produce tennis shots that should be declared illegal"

"I would suggest that his next opponents don't look to me for advice"

"I just don't get it. The pigeon was already dead, we found it in the road. And no other censor has objected. What is the problem with you, English? You killed millions of Indians and Africans, and yet you go nuts about the circumstances of the death of a single Serbian pigeon. I am touched you hold the lives of Serbian birds so dear, but you are crazy. I will never understand how your minds work."
