Novak Djokovic is honoured to be classed among the greats of the game and says making history motivates him to win even more titles.

Djokovic's straight-sets demolition of Andy Murray on Sunday ensured the Serb moved level with Roy Emerson's all-time best six Australian Open crowns.

He also takes his Grand Slam tally to 11 overall, climbing joint-fifth in the pantheon of champions alongside Bjorn Borg and Rod Laver.

Above Djokovic and in his sights are Emerson on 12, Pete Sampras and Rafael Nadal on 14 and at the top, Roger Federer with 17.

"Every Grand Slam title is very significant in its own way - here, because I managed to make history and equal Roy Emerson's six Australian Open titles," Djokovic said.

"I'm very honoured to be mentioned alongside legends of our sport like Bjorn Borg, Rod Laver, and win as many Grand Slams as they did.

"I can't lie and say I didn't think about it. Of course it was in back of my mind. Coming into the court I knew that I have a chance to make the history.

"Of course it served as a great motivation, as a great imperative to play my best. I tried not to think about it too much, but it was there as an encouragement, as a positive feedback, and a goal."

The victory over Murray was Djokovic's 17th consecutive tournament final, fifth in Grand Slams, and as a 28-year-old with no serious injury concerns, there are likely to be many more to come.

Silverware did not always come so easy for Djokovic who, after winning his first in 2008, went 11 major tournaments before sealing a second success.

Now, however, he has won five out of the last seven available and the world number one says his secret lies in staying true to himself on court.

"There's something I've found out in the previous years in my career is that you can't separate yourself professionally and privately - you're the same person," Djokovic said.

"So all these emotions that are maybe trapped, that occur in your private life, the issues, the problems that we all face, you need to surface them. You need to find a solution.

"In these particular matches when it goes down to very few points, when you're challenged in every aspect of your being, if there is something under the surface, it will come out and it will play against you.

"It will be your worst enemy."
