Rafael Nadal has said that he wants to have fun at Wimbledon this month.
The Spaniard has slipped to 10th in the world rankings due to injury and may need to beat one of the top four seeds to reach the semi-finals.
Nadal told Wimbledon.com: "Playing on clay, obviously when I had the feeling I was playing at my best, the feeling is I have time for everything, and I have the possibility to play tactically. I had the possibility to play with different styles, to be aggressive, more defensive. That makes me feel under control almost all the time.
"On grass is a different story. On grass, the feeling is you have to be very focused all the games, every point. You cannot have two mistakes in a row, or three mistakes in a row with your serve because almost you lose a set.
"So it's a big difference and a good chance to go to the net more. It's a good chance to do different things that you are not doing very often on the tour. I'll try to have fun with that."
Nadal will meet Brazilian Thomaz Bellucci in the first round.
