Novak Djokovic says there are no secrets between himself and Andy Murray as the duo look to put together a victorious run at the Australian Open.

Djokovic is chasing an 11th Australian Open title - a success that would see him move onto a record-breaking 25 grand slam titles.

He has enlisted the help of old foe Murray, who the Serbian beat in four Australian Open finals, as a coach for the tournament, which starts on Sunday in Melbourne.

Murray has already been heavily involved in Djokovic's preparations, with big crowds having flocked in to the 37-year-old's practice matches.

And Djokovic says all the cards are now on the table as he looks to Murray for guidance.

"I must say at the beginning it was a bit of a strange feeling to be able to share the insights with him, not just about the game but about how I feel, about life in general," Djokovic told reporters.

"Not in a negative way, but just in a way I have never done with him because he was always one of my greatest rivals.

"We were always kind of hiding things from each other. Now all cards are open on the table. That's what he demands.

"I am 100% supportive of that kind of communication method."

Djokovic, who will face Nishesh Basavareddy in the first round, added that he sees Murray as an inspiration.

"Andy really has inspired myself and a lot of people around the world," he said.

"I think that his unique perspective on my game is the fact that he has played me for 25 years. He knows my strengths and weaknesses."
