Novak Djokovic renews his affinity with the Australian Open next week as Roger Federer chases more elusive Grand Slam glory and Rafael Nadal battles wear and tear heading into the new season.

The world No 1 from Serbia has won four of his seven major titles in Melbourne and relishes the fast hardcourt, making him the player to beat in the year's opening Grand Slam.

Djokovic was upset by eventual champion Stan Wawrinka in last year's quarterfinals, ending his 25-match winning streak at Melbourne Park, but he went on to land Wimbledon and make the semifinals at the US Open.
