Alexander Zverev asked for a spectator who heckled him over domestic abuse allegations to be kicked out of his Munich Open quarter-final.

The German number one seed was serving at 5-5 in the second set against Dutchman Tallon Griekspoor when the fan shouted: "Let's go, you wifebeater."

Zverev spoke to chair umpire Fergus Murphy and could be heard saying "Fergus, please kick him out".

It is not clear if the spectator was ejected from the stadium.

In January, Zverev was heckled by a spectator during the Australian Open men's singles trophy ceremony.

As he stepped up to receive his runners-up trophy, a spectator loudly shouted: "Australia believes Olya and Brenda."

The 27-year-old was accused of violence by his former girlfriend Olya Sharypova in 2020 and of domestic abuse in 2023 by Brenda Patea, with whom he has a child.

Zverev has repeatedly denied both sets of allegations and a Berlin court case brought by Patea was discontinued last year.

Zverev won the match on Friday against Griekspoor 6-7(6) 7-6(3) 6-4. He will face Hungary's Fabian Marozsan in the semi-final on Saturday.
