Novak Djokovic produced one of the most remarkable performances of his career to defeat two-time defending champion Jannik Sinner and reach an 11th Australian Open final.
The 38-year-old is the oldest man in the open era to achieve the feat, and he battled for four hours and nine minutes to do so, finally clinching a 3-6 6-3 4-6 6-4 6-4 victory just after 1.30am.
