“With all the injury problems we have in men’s tennis at the moment, I’m happy to still be standing.”

My game is a lot about footwork. If I move well, I play well.

My family is the thing I miss most on the tour.

I always knew I had something special.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.

It is always in my mind still that I can crush anybody. That’s not an issue. But I think that is the same for most athletes. If you don’t believe you can win tournaments anymore, then you can’t do it.

You always want to win. That is why you play tennis, because you love the sport and try to be the best you can at it.

I always had the dream that, once I became No 1 in the world, that if I had a child I hoped I would have it early enough so the child can see me playing.

I have a very strong opinion. I’m absolutely against it. I’m against the challenge system. I’m for the way it is right now. Don’t change that.

I have learnt to be even more patient.

I am thinking more and more about what I want to and can do after my days as an active athlete. Thoughts like family and marriage also cross my mind more and more often.

One or two years ago, I didn’t know who I was on court and I used to swear a lot. But now I’ve learned how to cope and can therefore win 10 matches in a row. I want to be remembered as a good player rather than an idiot on court.

I’m playing great tennis. I’m enjoying the tour, having fun with the fans off the court. I’m loving it now.

I’m proud to be a symbol like the army knife or the mountains.

The nicer the point, the more — the better I feel, the more excited I get. But I never play that my opponent looks stupid. I think that is wrong. I have too much respect for every opponent I play.

What I think I’ve been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.

Clearly, when you win everything, it’s fun. That doesn’t necessarily mean you love the game more.

It is only god who creates. Man merely arranges.

No man is hurt but by himself.

Man cannot live without joy; therefore when he is deprived of true spiritual joys it is necessary that he become addicted to carnal pleasures.

To one who asked what was the proper time for lunch, he said, “If a rich man, when you will; if a poor man, when you can.”

How is it they live in such harmony, the billions of stars, when most men can barely go a minute without declaring war in their minds?

The greatest kindness one can render to any man consists in leading him from error to truth.

Nothing created has ever been able to fill the heart of man. God alone can fill it infinitely.

As a matter of self-preservation, a man needs good friends or ardent enemies, for the former instruct him and the latter take him to task.
