Tennis is beautiful when you can see tactics, when players don't just react but are able to act and think.

You have to accept both losing and winning well. I've stayed calm when I'm winning and I've stayed calm when I've lost.

The US player Andy Roddick reaches speeds of 220 kilometers per hour when he serves. If I train with him every day, I will later be at an advantage against a player whose service crosses the net at 190 kilometers per hour.

I will do as I usually do. Tomorrow is going to be a day like any other day.

I was passionate about soccer. I still am. Odd, though - playing soccer always made me much more anxious than playing tennis. On soccer days, I'd be out of bed by 6 in the morning, all nervous. But I was always calm when it was time for a tennis match. I still don't know why.

I will work day after day like I did my whole life ... I'm not going to change anything.
