Novak Djokovic targeting Australian Open glory is nothing new - but there will be one major difference this time around as great rival Andy Murray joins his team. The 37-year-old Serb, who is chasing a record 25th Grand Slam singles title, announced the surprise appointment of long-time friend Murray in November. Djokovic shared countless memorable moments and numerous battles for the sport's biggest prizes with Britain's three-time major winner Murray, who retired from tennis last year.

The first of their seven showdowns for a Grand Slam title arrived at the Australian Open in 2011, with both players aged 23. The final hinted at the seismic battles to come but, on this occasion, Djokovic regained the title in dominant fashion. He condemned Murray to a third defeat in major finals, claiming a 6-4 6-2 6-3 win in a tense encounter which had begun with a 15-minute opening game.
The next meeting between the two in Melbourne went the distance, and their five-set, near five-hour .
