Novak Djokovic refused to go away and Roger Federer just could not find enough shots to see off his opponent, giving the Serbian his second US Open title and tenth Grand Slam in all.

In a US Open final that last three hours and 20 minutes, Djokovic showed his fighting abilities, even when not at his best, to stop Roger Federer's bid for a sixth US Open title and 18th Grand Slam, by beating his great rival 6-4, 5-7, 6-4, 6-4.

This was not a US Open final littered with quality and unbelievable shots – yes, there were a fair few of those – but one of missed chances, particularly for Federer, who will leave New York knowing full well that he let a major slip through his hands.

Djokovic, though, again showed why he is the best player in the world, refusing to go down, even when the vast , majority of the Arthur Ashe crowd was pulling for Federer, and this title, his third major of 2015, was the icing on what has been a wonderful year for the world number one.

Federer, meanwhile, said he hopes to finish the year on a high after this disappointing loss in the final. "I am playing a good year, you know," said the 17-time Grand Slam winner. "I'm playing good tennis. I am happy with where my level is at. I'm able to be, you know, consistent, very consistent.

"I'm able to beat the best players regularly. Cincinnati obviously was a great feeling beating world No. 1 and world No. 2 in the same week. I don't think I have done that before.

"And then of course it's also disappointment. Lost too many times in finals. But at the same time, I did win my tournaments, the ones I was supposed to.

"The one I got I was very got happy the way I was playing. Year's not over yet. I usually do have a strong finishes to the season, and I hope I can do that again."
