There'll be a repeat of last year's French Open final when the champion and world tennis number one Roger Federer plays Robin Soderling tonight for a place in the semi-finals.
Soderling knocked out Rafa Nadal last year in Paris and beat Federer at the start of the year in an exhibition match.
However Soderling's lost all 12 of his ATP tour matches against Federer, who says he's been impressed by the Swede's very strong, forehand, backhand and serve.
In the other quarter-finals Nadal plays Nicholas Amalgro while Novak Djokovic meets Jurgen Melzer and Tomas Berdych takers on Mikhail Youzhny
