It's his life. The rest only concerns him." Rublev comments on Medvedev's incident at the US Open

Daniil Medvedev's outburst at the US Open against Benjamin Bonzi made headlines around the world, and many players have been asked about it.
Andrey Rublev also spoke about the incident, defending his friend. He stated: "I'm not the best example to follow, because my usual behavior isn't a good example either.
How can I judge someone if I sometimes behave the same way? And how can I judge someone who has been world number one and a Grand Slam champion?
It's his life. If he wants to change and needs help, he can count on me, on many other friends. He has a family who will help him… It's his life and these are the decisions he has to make.
Obviously, he's a very kind person, he's super nice. The rest only concerns him. Only he knows what's going on.
