It wasn't always so. Rochus, who is from Belgium, and Federer, who is from Switzerland, were teenage doubles partners. They won the Wimbledon junior doubles title in 1998.
Before that, Rochus beat him regularly.
``I remember him when we were 13 years old. He was always losing 6-0, 6-1 against everybody in the under-14 tournament,'' Rochus said.
But that was then. Federer, who just turned 24, has been No.1 in the world for 81 weeks, the seventh-longest period ever.
``We were almost laughing at him, and now he's laughing at us,'' Rochus said. ``He's No.1, easy. And really, when he was young, at the beginning, he was really bad.''
