Zverev was one of the players to feature at Novak Djokovic’s Adria Tour exhibition event earlier this month, where seven people tested positive for coronavirus, including Djokovic and three other players.
Players were photographed playing basketball and attended a nightclub in Croatia, leading to Krygios describing the event as “boneheaded”.
Following the event, Zverev released a statement “deeply apologising” to anyone put at risk and pledged to self-isolate for 14 days.
However, in a since-deleted video posted on Instagram by German fashion designer Philipp Plein, Zverev is seen dancing at a club in Monaco.
Morning, normally post pictures of the Wimbledon queue around about now, but instead, this from the Nick Kyrgios Instagram re Zverev.
All very 2020. (Ps includes f-words and video-recording whilst driving ...). pic.twitter.com/lKSWELfu7z

“I wake up and I see more controversial things happening all over the world. But one that stuck out for me was seeing Sasha Zverev again, man, again,” Kyrgios said.
“How selfish can you be? if you have the audacity to put out a tweet that you made your management right on your behalf saying your’re going to self isolate for 14 days and apologising to the public for putting their health at risk at least have the audacity to stay inside for 14 days, my God, have your girlfriend with you for 14 days.
“Jesus, man, this tennis world is p****** me off. How selfish can you all get?”
Kyrgios has been vocal in his criticism of some players' negligent approach to the pandemic, while also questioning the ATP and USTA, who have confirmed plans to begin the US Open in late August despite several countries still imposing quarantine measures and travel restrictions.
