Novak Djokovic beat Andy Murray in four sets to win a fifth Australian Open title

World No 1 Novak Djokovic beat Andy Murray in four sets to win a fifth Australian Open title in Melbourne on Sunday.

Djokovic's 7-6 (7-5) 6-7 (4-7) 6-3 6-0 win means that Murray has now lost his sixth Grand Slam final - four in this tournament - to the Serb.

Since Djokovic won his first major title in 2008 he has compiled a 47-3 record in Melbourne. His reign means he has the record for most Australian Open titles in the Open era, one behind Australia's Roy Emerson who dominated in the 1960s.

"I am so privileged and honoured and grateful to be standing here as a champion for the fifth time and to be in the elite group of players with Sir Roy Emerson and Rod Laver and all the legends of our sport," said the Serb.

"It's an honour playing in front of you, thank you very much.

 Djokovic has now beaten Murray in three of his four Australian final losses following earlier wins in 2011 and 2013, although the Scot mastered him in his two major triumphs at the 2012 US Open and 2013 Wimbledon.

"Tough luck tonight, Andy, you are a great competitor, you fight a lot and I want to congratulate your team and wish you all the best for the rest of the season," he said.

The victory means Djokovic stays at world No 1 on the next ATP rankings when they are released on Monday, with Murray moving to four from his current sixth.

"We have put in a lot of hard work to try and get back in this position after what was a difficult year last year," said Murray, referring to injuries that dogged his 2014 season.

"Unfortunately, I couldn't quite do it tonight but I was a little bit closer than I was a few months ago and I will keep working hard to get there.
