Novak Djokovic puts his 33-match unbeaten Australian Open run to the test against Jannik Sinner on Rod Laver Arena on Friday.

The world number one has not been beaten at Melbourne Park since a fourth-round loss to Chung Hyeon back in 2018, with only two opponents in the intervening six years managing to push him to five sets.
