I must be the only player in the world who ever injured himself for a tournament by stepping on a shell on the beach. I don't know what I'm going to do.

If I can't serve on grass, I can maybe help cut the grass, paint the lines and serve some strawberries.

Winning Wimbledon was a great feeling and it is still a great feeling. It has given me so much confidence.

When I started in my career, my sister was very sick so I play for her because we didn't have money.

If you are given a lot of money without having to work for it, you won't appreciate it as much as if you made it yourself.

When you are winning too much, sometimes you think you should never lose again. I am learning to lose.

Although we didn't have much when I was growing up in Split, Croatia, my parents always tried to ensure that my sister and I had the things we needed, and it was enough for us.
