We'll try and be very aggressive, we'll try and speed up and change gears, and we'll see who's going to win.
My serve can get better, for sure. It's not just about serving bombs, but positioning, variation in speed, in spin.
All sports are continuously developing, but what they all have in common is that the speed is increasing. That's also true of tennis; the ball is getting faster and faster.
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.
Today people hit the ball with much more strength. Almost every player is capable of playing a winning stroke from any position. This means the balls arrive more quickly. If you want to reach them, you have to slow down from a high speed or suddenly change direction. These are moments when you can injure yourself, and that's what wears us out.
