( CNN ) -- Rafael Nadal will face Roger Federer in Sunday 's final ATP World Tour Finals at the O2 Arena in London . Federer dispatched semi-final opponent Novak Djokovic in straight sets 6-1 6-4 on Saturday evening , while Rafael Nadal beat a determined Andy Murray 7-6 ( 7-5 ) 3-6 7-6 ( 8-6 ) in the first semi-final earlier in the day . Federer was in ruthless form in the opening set , holding his opening service game to love and then wasted no time breaking the Serb 's serve in the next . Djokovic managed to open his account in the fourth game , but there was no stopping the World No.2 after that as he secured a double break in the sixth , before polishing off the set with trademark efficiency . The Serb started the second set more promisingly , holding his opening two service games and breaking Federer in between to establish a 3-0 lead . But Federer broke back in the fifth to restore parity , and broke again in the ninth with a series of wonderful forehand winners , before holding serve to win the set and the match . Tennis aces feel like rock stars . Earlier in the day , World No.1 Nadal narrowly overcame Britain 's Andy Murray in an epic three setter 7-6 ( 7-5 ) 3-6 7-6 ( 8-6 ) . Despite a spirited display , Murray 's pre-match pessimism earlier in the week turned out to be well-founded , as the Spaniard eventually prevailed in a grueling encounter . Murray produced his best tennis of the week and there was little to choose between the two men in the first set as they traded some thumping forehands . But there were few alarms on serve as the set progressed and a tiebreak was the inevitable conclusion . Nadal secured the first mini-break to go 3-1 up and soon extended his lead to 5-2 . But Murray fought back , winning the next three points to level up at 5-5 . But a miscued running forehand by the Scot handed Nadal his first set point which he seized , attacking Murray 's serve before delivering a deft drop volley . The first six games of the second set went with serve , but in the seventh Murray earned himself three break points . Nadal managed to save them all , but an over-hit return at deuce handed Murray a fourth opportunity which , this time , he secured with a crosscourt backhand winner . Murray held his next service game to lead 5-3 and when Nadal faltered again on his serve Murray took full advantage and ensured -- to the delight of a rapt crowd at the O2 Arena -- that the match would go to a deciding third set . Nadal started it the stronger , breaking Murray in the third game and looked as if he would close out the set and the match comfortably . But Murray claimed the 10th game to level the scores at five games apiece as the match headed towards a deciding tiebreak . Murray had the better of the early exchanges and opened up a 4-1 lead only for Nadal to level things up at 4-4 . The Spaniard then seized the initiative which saw him close out the tiebreak 8-6 and take the match to set up a 22nd meeting with Federer . Nadal has an impressive 14-7 head-to-head record against the 16-time Grand Slam champion , according to atpworldtour.com . Their last meeting was on clay at ATP Masters event in Spain earlier this year , where Nadal won in straight sets and in their last ten meetings the Spaniard has prevailed seven times . But it 's currently honors even in their hard court meetings with each player having won on three occasions .
