It's the biggest match of Alex de Minaur's career - an Australian Open quarter-final against reigning champion and world no.1 Jannik Sinner. De Minaur has never been to the last four in a major and he will have to overcome an 0-9 head-to-head record with the Italian champion.

Home favourite Alex De Minaur will face Jannik Sinner in the quarterfinals of the Australian Open after the world number eight beat world number 42 Alex Michelsen of the US 6-0 7-6 6-3 in the round of 16 Monday.
