Roger Federer closed on a first ever Paris Masters final when he beat Richard Gasquet to reach the quarterfinals, after Novak Djokovic and Andy Murray had swept into the last eight.
Federer, the third seed, broke the home favourite in the opening service game of their evening match at Bercy Arena and secured another break when Gasquet double-faulted at 2-4 down, before clinching the set with a nonchalant volley.
After an early exchange of breaks in the second set, Federer broke again and went on to complete a 6-2, 6-4 victory with an inside-out forehand winner on his first match point.
Federer will meet Juan Monaco in the last eight, after the unseeded Argentine survived two match points against American seventh seed Mardy Fish, who was forced to retire with a hamstring injury when leading 6-1, 6-7 (6/8), 2-1.
Djokovic overcame a first-set wobble to beat Serbian countryman Viktor Troicki 4-6, 6-3, 6-1.
The world number one was broken twice in the first set and folded on Troicki's first set point when he drove a backhand into the net.
Djokovic went 2-0 up in the second set, only for Troicki to level, but the top seed broke again to go 4-2 ahead with a cross-court backhand winner before levelling the match.
Troicki had lost his last nine encounters with Djokovic and the 15th seed's resistance broke apart in the third set, enabling the 2009 champion here to complete his comeback and take his place in the last eight.
"It was a difficult match," said Djokovic, whose participation in the tournament had been threatened by the recurrence of a shoulder problem.
