Andy Murray has only been working with Novak Djokovic for a short period of time, but he has already felt comfortable enough to question his commitment.

Days after joining Novak Djokovic’s coaching team, a 2-year-old clip of Andy Murray making fun of the Serb’s diet, resurfaced online.

Djokovic announced this past week that Murray would join his team as a coach at least through the 2025 Australian Open.

Andy Roddick analyzed what was the tennis news of the year: Andy Murray will be Novak Djokovic's coach , starting with the pre-season that will lead the Serbian champion towards the 2025 Australian Open and towards the rest of the season.

Novak Djokovic has taken on Andy Murray as his coach for the Australian Open. It makes sense to put half of the original Big Four in men's tennis together again.

Djokovic admitted that his phone call with Murray caught the Scot "a little off guard" but stressed that the pair "connected really fast". The 37-year-old is said to have only taken a few days to agree to the role, less than four months after retiring at the Paris Olympics.

Novak Djokovic launched his career in the shadow of Roger Federer and Rafael Nadal but has surpassed them both and is widely considered the greatest player of all time.

Novak Djokovic says his decision to appoint former rival Andy Murray as his coach was "a surprise to everyone" but is "exciting for tennis".

Tennis fans were left stunned as Andy Murray and Novak Djokovic announced a new coaching partnership earlier this year. The move signals a bold ambition from Djokovic, who experienced a Major-less year and has been without a permanent coach since March.
