Xavier was on a Belgian sportshow. Sabine Appelmans works for them and every week she makes a little reportage with 2 Belgian topsporters. One of them tries to learn the other one's sport.
Xavier had to show a soccer player how to play tennis. But it was kinda strange because he couldn't explain to the guy how to hit a backhand...
He told him he uses a grip no one else uses and teached the guy how to use that.
At the end they played 3 games aginst eachother, which Xavier won!
That's it! Not much!
