The stakes could not be higher as Novak Djokovic and Carlos Alcaraz square off in an Australian Open quarter-final clash of the tennis titans on Tuesday night.
So much history is on the line as 21-year-old Alcaraz, bidding to become the youngest man to complete a career grand slam, stands in the way of an unprecedented 25th major singles crown for Djokovic.
Sixteen years may separate the two, but already Djokovic and Alcaraz have forged a compelling rivalry highlighted by two Wimbledon finals, a Paris Olympic gold medal showdown, and semi-finals at Roland Garros and the 2023 ATP season-ending championship.
