Novak Djokovic dispensed with the Darth Vader mask but still proved too daunting an adversary for American John Isner as he reached the Paris Masters quarter-finals with a 6-7(5) 6-1 6-2 victory on Thursday. The Serbian world number two,who entered the Bercy arena last year as the infamous Star Wars villain,survived a barrage of aces from the towering Isner before ruthlessly dispatching him. I know,I know. It's my fault. I was not prepared enough . so I'm going to have to be pretending that I'm myself this year. No Darth Vader, Djokovic,who watched nine aces fly by him in the opener,told a news conference. Glimpes of form Roger Federer showed glimpses of his brilliant best as the 17-times grand slam champion outclassed German Philip Kohlschreiber 6-3 6-4 to advance into the last eight. A day after securing his place at next week's ATP World Tour finals,the Swiss was comfortable throughout as he set up a clash against Juan Martin del Potro who beat him in the Basel final last week. Canadian Milos Raonic,who still has a glimmer of a chance of snatching one of the last two qualifying spots for the London season-ender,was up against Czech sixth seed Tomas Berdych later. The best-placed in the race is Djokovic's next opponent,Swiss seventh seed Stanislas Wawrinka,who almost secured his place with a 6-3 6-2 dismissal of Spain's Nicolas Almagro. Almost means it's not yet done,but it's always a good thing to win those matches and of course to become closer to go to London, the Swiss told a news conference. Either I win one more match or the others lose before I do,or before the final for Raonic.
