Novak Djokovic threw a tantum after being ignored by his own box during his Australian Open quarter-final win over Taylor Fritz on Tuesday.
The 24-time Grand Slam champion was also seen blowing kisses to Nick Kyrgios and the McEnroe brothers in the ESPN commentary booth as he beat his American opponent over four sets to continue his title defence in Melbourne.
World No.1 Djokovic will face Jannik Sinner or Andrey Rublev on Friday in what will be the the 48th major semi-final for the 36-year-old, who looked furious as he was blanked by his own team against Fritz while trying to get their attention.
During one of the changeovers, Djokovic waved to his box and after getting no acknowledgement, he started throwing his hands in the air more aggressively.
