Transcript of Novak Djokovic appoints Andy Murray as coach for Australian Open

With one last wave to the crowd, Andy Murray exited Wimbledon's Center Court after his last match on British soil. It wasn't clear what the future would hold, apart from more golf and some quality time with the family. Four months on, it's all been revealed, with the first hint coming at 4:00 PM. He never liked retirement anyway, quipped tennis superstar Novak Djokovitch on social media, before revealing all call in this message.

I thought our story may be over. Turns out it has one final chapter. It's time for one of my toughest opponents to step into my corner. Welcome on board, Coach Andy Murray.

The news was confirmed by Murray. I'm really excited for it and looking forward to spending time on the same side of the net as Novak for a change, helping him to achieve his goals, he said in a statement. It certainly came as a shock.

I'm just so intrigued. I honestly think it's one of the most interesting tennis coaching relationships in the sports history. I mean, it's so unusual to have such a recently retired player linking up with someone who was their biggest rival as a player. It's amazing.

The plan is to prepare the 24-time Grand Slam champion for January's Australian Open. The Scot and the Serb have plenty of history. Born a week apart, the rivalry began as boys What followed were 36 professional clashes, Novak winning most. But it was Andy who would lift the Wimbledon Trophy in 2013 with a straight set win. Along with Roger Federer and Rafael Nadal, Murray and Djokovitch would complete the so-called Big Four. Novak is the only one still playing.

Djokovitch is obviously one of the greatest tennis players of all time, and he's coming to the end of his career. But this decision, I think, suggests how much ambition he still has.

Now, with his one-time foe on side, Novak will be hoping to smash his way into the recordbooks with the most Grand Slam wins of all time. Emma Burtchley, Sky News.
