WATCH: One of the greatest points ever as Stan Wawrinka shocks Novak Djokovic in US Open final

Superb tennis.

Swiss star Stan Wawrinka claimed his third grand slam title and he did it in impressive fashion, dispatching world number one Novak Djokovic in a 6-7, 6-4, 7-5, 6-3 victory. In a match that lasted just under four hours, the spectators at Arthur Ashe were treated to some truly remarkable tennis as the heat and humidity required Djokovic to twice call his trainer in the final set. The Swiss star had won just four of 23 previous matches against Djokovic prior to the final, but his win now means that Wawrinka has won all three of the Grand Slam finals he has played in. There were some truly astonishing rallies of attack and counter-attack during the match, none better than this one during the first set tiebreak. Some people have even referred to this 21-shot rally as one of the all-time great points. https://twitter.com/Eurosport_UK/status/775082153239416832 https://twitter.com/sluggahjells/status/775081345802440704 https://twitter.com/KelceyBradeTSN/status/775081149525745664 https://twitter.com/gutted27/status/775081120262197248
