Novak Djokovic declared the Australian Open his favourite Grand Slam after defeating Andy Murray in four sets in Sunday's final.

The Serbian is the first player to win three consecutive Melbourne titles in the Open era and was in jubilant mood after seeing off Murray 6-7 7-6 6-3 6-2, although he admitted he was pushed hard by his opponent in a match that lasted three hours and 40 minutes.

"It's definitely my favourite Grand Slam. It's an incredible feeling winning this trophy once more. I love this court," said Djokovic.

"It's been an incredible match as we could have expected. When we play each other, we always push each other to the limit.

"Physically I was just trying to hang in there, to play my game and focus on every point."

Djokovic battled back from 0-40 down in the second game of the second set to hold his serve, something he feels was crucial in the context of the match.

"He missed an easy backhand and I think mentally I just relaxed after that," he added.

"I just felt I'm starting to get into the rhythm that I wanted to. I was a little more aggressive and started to dictate the play."
