Novak Djokovic saw off Britain's Kyle Edmund on Thursday to reach his eighth Paris Masters quarter-final, where he will renew his burgeoning rivalry with Greek star Stefanos Tsitsipas.
The top seed, battling Rafael Nadal for the year-end world number one spot, needed seven set points in the first set before winning 7-6 (9/7), 6-1.
The 16-time Grand Slam champion is chasing a record-extending fifth Bercy title, but will next face world number seven Tsitsipas, who leads their head-to-head record 2-1.
Djokovic is hoping to tie Pete Sampras' record of finishing six years as the world's best player, but Nadal can be sure of denying the Serbian that achievement with a maiden Paris title this week.
The Spaniard takes on three-time Grand Slam title-winner Stan Wawrinka in his third-round match later on Thursday.
