The first time at age 5 and a half, when I took a racket in my hands and my father fed me some balls, I made 50 backhands in a row - didn't miss a single one.
I've been playing against older and stronger competition my whole life. It has made me a better tennis player and able to play against this kind of level despite their strength and experience.
I once played amateur tournament tennis six months without double-faulting.
The best thing about being 6'9'' is that it helps with my tennis game, especially with my serve.
Since I was little, I've watched Roger play on TV. To me, he plays almost perfect tennis. His technique is perfect. I also like him at the human level; he's a very good person on and off the court.
I was so horrifically bad at tennis.
I wish I could play like Roger Federer.
I think I'm a very powerful player; I can hit good groundstrokes.
Ivan Lendl was the best player I ever played. He was the first guy to bring the game to more of a power level and you could know that if he played really well you could get blown off court and that wouldn't happen against John McEnroe, Jimmy Connors or even Bjorn Borg or Guillermo Vilas.
There's no such thing as an open draw. At least for me - I mean, obviously for Roger Federer, I think every draw feels open for him - but for me there's no such thing as an open draw
There is no such thing as bad luck in tennis. Just bad technique.
Serena is tough to beat; to get over her in the rankings is hard.
I wasn't any good at playing tennis.
I'm 6ft 7in and I was a bit like a giraffe on the tennis court, though I did play at county level.
In 2015, there was no chance Djokovic would have an off day.
[In the modern game] you're either a clay court specialist, a grass court specialist or a hard court specialist... or you're Roger Federer...
I was playing good tennis up until 100.
He [Roger Federer] is the greatest natural talent in tennis I've ever seen. I love to watch the guy play, he's an awesome talent
Billie-Jean King used to take me out on court and say that she just wanted to watch my forehand. You can't get greater praise than that.
I've been around tennis, and I have a feeling for the sport. I still play tennis, and I can still do a lot of harm to a lot of people.
Roger [Federer], he brought tennis... one level higher. Normally he toys with everybody. With all respect to other players, he does whatever he wants on the court against them. It's incredible what kind of game he can play.
Everybody knows I'm not a clay-court specialist. I'm not feeling so well on this surface.
It's that I have a good personality and am a good tennis player.
I have a better backhand than forehand.
To play against Serena in a final is something special. You know you must play your best tennis.
