(REUTERS) - Top seed Novak Djokovic and defending champion Roger Federer advanced to the Western & Southern Open final on Saturday to set up a rematch of their title-deciding Wimbledon clash.

Djokovic, who beat Federer in the Wimbledon final for a second consecutive year last month, rallied to beat Ukrainian qualifier Alexandr Dolgopolov 4-6, 7-6 (7-5), 6-2.

Federer beat third seed Andy Murray 6-4, 7-6 (8-6).

Djokovic, who needs a win on Sunday to become the first player to claim all nine ATP Masters titles, lost the first set but escaped a nervy second-set tiebreak in Cincinnati that took the wind out of his 66th-ranked opponent's sails.

Completing the set of ATP Masters titles will be no easy feat for Djokovic with six-time Cincinnati champion Federer standing in his way.

The final sets up the latest instalment of their rivalry, knotted at 20 wins apiece.
