Novak Djokovic branded his defeat by Jannik Sinner to end his long unbeaten Australian Open run as one of the worst performances of his career.

The world number one’s 6-1 6-2 6-7 (6) 6-3 loss in the semi-finals was his first at Melbourne Park since a fourth-round defeat by Chung Hyeon in 2018, ending a 33-match streak taking in four titles.
