Novak Djokovic and Carlos Alcaraz will square off again in a Grand Slam after both stars won their fourth-round matches Sunday at the Australian Open.

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.

Novak Djokovic has put himself at loggerheads with the Australian Open’s host broadcaster by refusing to give any more on-court interviews until he receives an apology from anchorman Tony Jones.
