The retired Brit will coach his former rival at the opening Grand Slam of the year and quipped that his main aim is to ruin the Serb's hopes at the tournament as revenge for the anguish Djokovic caused him in Melbourne during his playing days.

Murray - who lost four finals to Djokovic at the event - said during the 'A Night with Novak' exhibition event: "Yeah, played here a few times. Could never quite go over the line unfortunately, this man was single-handedly responsible for that.

"So I'm now here to try and sabotage his chances of winning another one."

The former world number one revealed that working with Djokovic has been as he "expected" as his rival is "one of the best athletes of all time".

Murray said: "Look, it's been as I expected. You know, Novak is not just one of the best tennis players of all time, he's one of the best athletes of all time.

"I expected him to be an extremely hard worker, very diligent [and] always looking to improve. So it's as I expected, and looking forward to competing now."

It was announced in November that Murray and Djokovic would be teaming up at the Australian Open and Murray admits that he was taken aback by the 24-time major winner's offer as he had been focused on golf after ending his playing career last summer.

He recalled: "I was on the 17th hole of the golf course and the guy I was playing with said to me, ‘Do you know what’s next?' I was like, ‘No, not really’.

"He said, ‘Do you have any plans to do any coaching’? And I said, ‘Honestly, I can’t think of anything worse to do right now’.

"And then 30 minutes later I was in the car and I called Novak, and then we had a conversation, and he asked if I would be interested in helping, which I obviously wasn’t expecting.

"I said to him, ‘Look, I need to think about it and talk to my family’. So I spoke to them and, after a couple of days, I thought that it was a pretty unique opportunity and experience."
