Alexander Zverev did not win the first Grand Slam title of his career even at the 2025 Australian Open. The German champion was an underdog against Jannik Sinner in the final, but he thought he could put the world number 1 in serious trouble and maybe achieve a feat that would change his career.

After getting overrun by Jannik Sinner 6-3, 7-6 (4), 6-3 in the men’s singles final Saturday night to give the world No. 1 player a back-to-back victory in Melbourne, fans called out Zverev for his dark past, referencing two of the German player’s ex-girlfriend’s who have accused him of domestic abuse.

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.
