MONTPELLIER (France) (AFP) French number one Jo-Wilfried Tsonga beat Portugals Federico Gil 6-3, 6-4 to qualify for the quarter finals at the Montpellier ATP event. Despite numerous break points against him the second seed came through his second round match courtesy of his attacking game and 11 aces to signal a return to form after a three month spell struggling with a left knee injury. I took hold of the match well against a player who can be dangerous because he already had a match under his belt, said Tsonga. I was not apprehensive from a physical point of view. To beat a Federico Gil, is a good thing but that does not build-up my confidence. I only have three or four victories behind me. I need reassurance and for that, I need victories over players close to the top 10 in the world. Also through to the last eight was the Russian top seed Nikolay Davydenko, who defeated German journeyman Mischa Zverev 7-5, 6-3.
