Novak Djokovic has reacted to the crowd at the Australian Open booing after he decided to retire from his semifinal against Alexander Zverev. The Serbian tennis player, 37, had taken to the court with his left leg heavily taped following Tuesday’s injury.

The rise of Jannik Sinner and Carlos Alcaraz vanquished Djokovic's inevitability at the Australian Open, but he is still the main character.

Novak Djokovic admitted “he tried” but was forced to pull out of the Australian Open a set into his semi-final against Alexander Zverev due to injury. There had been doubt about the Serbian's fitness until he took to the court after he suffered a left leg injury during his quarter-final against Carlos Alcaraz on Tuesday.
