With me, you never know what is going to happen

Since retiring I have spent a lot of time with my family, on my boat, and playing football.

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.

At her birthday, my seven-year-old daughter will say that she wants these big cakes and certain expensive toys as presents, and I can't say no to her. It would just break my heart. But when I was little, for birthdays we just played outside and we were happy if we got any cake.

The trouble with me is that every match I play against five opponents: umpire, crowd, ball boys, court, and myself.

Ivan Lendl's never going to be a great player on grass. The only time he comes to the net is to shake your hand.

I just try to play tennis and don't find excuses. You know, I just lost because I lost, not because my arm was sore.
