But Medvedev wasn’t having any of it. The world No 1 admitted that he usually felt bad when he showed any unsportsmanlike conduct towards a rival but that wasn’t the case with Zverev as there was no love lost between them. “So I usually feel bad when something on court happens and let’s say I’m not fair play, because I know sometimes I’m not,” he said.

“Sascha is living in his own world. Yeah, Sascha, when he loses, we can find maybe 25 interviews of him where he does say some strange things.” Referencing some other “kind” guys, the 2021 US Open winner added: “Sascha is not this guy.

“Sascha is not like Casper [Ruud], he’s not like Diego [Schwartzman], he’s not like Andrey [Rublev. When he says someone is not fair play, you’re like, ‘Okay, great. Look at yourself in the mirror.’” It remains to be seen what Medvedev makes of Zverev’s latest comments after renewing the row seven months later. But the world No 3 let his tennis do the talking when he beat the German again during last week’s ATP Finals.
