"In the field, you never know if you dive - says Jo-Wilfried Tsonga at The Tennis Space - Do you just dive, do not you think. If the volée is too far, you have to do it. If you think about it too much, you will not dive. The soil is hard and you'll get hurt but when the ball is far away, you can’t afford the luxury of thinking too much, you just have to dive. It 's a natural thing. I did not pay much attention to Becker’s dips, but that’s something I've always loved. You don’t hurt too badly on the grass and the public likes. I love it when I dive and I win the point, is like winning the entire match. The most important thing is the impact with the ground, you have to roll. It' s the most difficult thing. You don’t think to dips, but then you have to take the best position to not get hurt. And keep watching where the ball is going. "
