The history between Daniil Medvedev and Stefanos Tsitsipas is an interesting one that featured a very heated exchange a few years ago. Since then they share a rivalry albeit with much more respect than before. Medvedev was asked about the whole 'toilet break' thing and his response was:
"It’s tough to answer because a lot of things [are] going through my head because your question is a bit tricky, in a good way. I want to say, you know, we all need to go to change sometimes clothes."
He continued:
“Somebody does it five minutes, six minutes, eight minutes. What happened with him and Murray happened, he got booed – at least next match don’t go out for eight minutes [again]. And that’s what he did."
Medvedev finished up his though by saying:
“So, if you remember 2019 – I did a mistake. Well, I was not continuing to do it every other match. Otherwise, the crowd would not go behind me. So, that’s the only advice I can give, you know. (Laughs) I mean, he has his own life, so he probably won’t listen to my advice.”
