Novak Djokovic produced a clinical performance at the O2 to set up a showdown against six-time champion Roger Federer in Sunday's ATP World Tour Final.

World No 1 Djokovic produced a spellbinding performance to cruise past Rafael Nadal 6-3 6-3 in a one-sided contest illuminated by several displays of brilliance while Federer, reached his 10th final in 14 appearances by beating fellow Swiss Stan Wawrinka 7-5 6-3 in the evening clash.
Djokovic was at his serene best from the very first serve of the match - worryingly, Nadal was also striking the ball crisply from the get-go yet was still brushed away in the opening exchanges.
The first game was perhaps the best of the match as Nadal, against the serve, bludgeoned a pair of fantastic forehand winners that had the crowd on their feet but they weren't enough to prevent Djokovic holding.
The Serb then struck four consecutive winners in Nadal's first service game before holding to go 3-0 up. Nadal was deservedly on the scoreboard next but Djokovic, almost riled by losing a game, responded with a brilliant lob to make it 4-1.
Djokovic's serve was not threatened, and he noticeably caused Nadal a host of problems with his deceptively intricate delivery. He cruised over the line for the first set and almost caused a break in the opening game of the second.
Nadal was able to hold, with a significant battle underlined by a fist pump when he eventually won, and the first four games all went with serve.
Djokovic earned the first break of the second set to go 3-2 ahead, winning four consecutive points off Nadal's serve. The effort required the Serb's best tennis, as he outlasted the Spaniard in a rally.
He broke for the second time, crucially, to win the match after outlasting Nadal in a back-and-forth tussle.
The world No 1, with this win, tied his head-to-head record with Nadal to 23 wins apiece.
The 34-year-old Federer fell 4-2 behind in the opening set but rattled off four consecutive games to move ahead and cruised through the second set with smooth efficiency.
Wawrinka saved a match point at 2-5 but 17-time Grand Slam champion Federer was cruising by this point and ended the contest with a straightforward service game.Djokovic, who won the Australian Open, Wimbledon and the US Open this year and reached the final at the French Open, is a four-time champion at the season-ending tournament. And although Federer has won it a record six times, no one has won four in a row.
