Alexander Zverev was heckled from the stands during the awards ceremony after the Australian Open men’s final. A protester in the crowd repeatedly screamed out: “Australia believes Olga and Brenda.”Many tennis fans in the stands and a number of those watching at home unfamiliar with the background to the outburst would have wondered what the commotion was about.

World No. 2 Alexander Zverev was forced to address previous domestic abuse allegations made against him after he was heckled by a member of the crowd after the Australian Open final on Sunday.

Alexander Zverev didn't want to talk too much about his domestic violence allegations but shut down a protester by stating that she was probably "the only one in the stadium" who believed in that. On Sunday, Jannik Sinner handed a heartbreaking 6-3 7-6 (4) 6-3 loss to the second-seeded German in the Australian Open final.
