The top seed Novak Djokovic is into the quarter-finals at the Montreal Masters tennis tournament and is the last of the top players remaining after Roger Federer fell to Jo-Wilfried Tsonga.
The newly crowned world No.1 claimed his 50th win of the season, beating Croatian Marin Cilic 7-5 6-2 as he closed in on his ninth title for 2011 while Federer lost to Tsonga for the second time this summer, going down 7-6 4-6 6-1.
The match came weeks after the burly Frenchman beat the Swiss master in the Wimbledon quarter-finals, when he staged an incredible comeback from two sets down.
But the 16-time Grand Slam champion Federer says he's playing well and still has the Cincinnati Masters before the US Open, which starts on August 29th.
