Don't get too excited when I am winning, and don't get too depressed when I am losing. Just keep it cool.
I pay the bills, I pay for everything.
You're playing or you're not playing. If you're playing, so just shut up and play.
There is no such thing as a perfect player; it doesn't exist.
Me, I don't need money.
It's a pity that the tennis is really going down the drain. Every year it's getting worse and worse and worse. There has to be a radical change, and I hope it will be really soon.
