Novak Djokovic charged into the Australian Open quarter-finals and booked a mouth-watering encounter with Carlos Alcaraz before the Serb shifted the focus by snubbing the Grand Slam's official broadcaster and slamming them for mocking him and his fans.

Djokovic said he wants an apology from Channel 9 and Tony Jones, who called the 24-time Grand Slam champion overrated and a has-been during an on-air appearance.

Carlos Alcaraz and Novak Djokovic have set up a quarterfinal showdown at the Australian Open. Tuesday's contest will be their eighth head-to-head matchup, but their first at Melbourne Park and their first that is neither a semifinal nor a final.
