At the Australian Open, Djokovic suffered a leg injury that forced him to retire from his semi-final match against Alexander Zverev.

After withdrawing from Serbia’s Davis Cup tie against Norway, Djokovic is looking ahead to a return to the matchcourt.

Murray is unlikely to join Djokovic at the Qatar Open, but their reunion will not be far away if the Indian Wells reports are true.

Paul Annacone says what he thinks about Andy Murray coaching Novak Djokovic again

Paul Annacone knows what it is like to coach top players, having helped Roger Federer for three years that includes his penultimate Wimbledon title victory in 2012.

The American has coached multiple top Grand Slam champions including Pete Sampras, Stan Wawrinka and Sloane Stephens.

When speaking on the Tennis Channel podcast, Annacone discussed the latest news surrounding the Murray-Djokovic partnership and revealed the big questions that he has going forward.

“You have Andy Murray sitting in your box who has a wealth of information and to have that kind of information that so few people do that he can share with Novak, I think that’s really important,” said Annacone.

“But the most important thing is the dynamic between those two. As it with every relationship and coaching relationship with the player. It’s how do they communicate? How much buy in is there?

“I think the fact Andy has so much credibility with Novak is huge. I actually think the fact he is not going to be around all the time is really helpful.

“To me the biggest question isn’t about them, it’s kind of about Andy. I am just surprised Andy wanted to get back in this quickly. I thought he would take a moment and a breath and sort things out, but it shows us all about his passion.

“He wants to help so much and be part of something and he loves competing and this is a way he can compete. The biggest challenge for Novak now, in my opinion, is Novak. It’s his body.”

What has Andy Murray said coaching Novak Djokovic is like?

Murray was surprised by Djokovic at the Australian Open in his first coaching job since retiring at the Paris Olympics last year.

Since having time to reflect since their first tournament together, Murray told the Sporting Misadventures podcast what he did to try and help Djokovic in Melbourne.

“It wasn’t so much ‘this is what you did wrong’, it was more like ‘this is what you do right’,” said Murray. “(It was) ‘when I was playing against you, you were doing this, it was so hard to play against for these reasons’.

“I was more like trying to emphasise the positives of when he’s playing well, this is what it looks like and this is what it feels like for the player down the other end. As a player you never know the speed of your own shot, the speed of your ball, what impact it’s having on the guy down the other end, what are they feeling.

“If I (had been) able to hear from Novak or Federer or (Rafael) Nadal when I was playing against them, ‘oh I hate it when you do this to me or when you hit this shot’, that would have been a huge, huge help to me to know that.”

Murray and Djokovic are set to reunite at Indian Wells, with the main draw beginning on Wednesday March 6.
