One Son Heung-min is more than enough to beat three of them

‌I don't know if they expected the public opinion to be entirely on their side by even resorting to retirement jokes, but it looks like they failed.
If there were really an issue with Son Heung-min, he could just address it through a press conference or an interview; otherwise, staying quiet is the best course of action. It's not like he's the type of person who would just leave just because someone tells him to.
