Novak Djokovic rates local hope Alex de Minaur's chances of a deep run at the Australian Open, saying it's no surprise to see the Sydneysider crack the world's top 10.
De Minaur beat the world No.1 for the first time, as well as fellow top-10 players Taylor Fritz and Alexander Zverev, at the United Cup in the lead-up to the Melbourne Park major.
