I'm surprised by how accurate these "national team rumors" are

I've always wondered, who is the one spreading those things?
The accuracy regarding the national football team seems to be quite high.
The rumors about the retirement of the '96 line came out immediately after the match,
and while many people were skeptical, it was eventually confirmed as fact.
The stories about Hong Myung-bo saying something to Son Heung-min during the World Cup,
and the story that Son Heung-min was in such a bad mood after the South Africa match that the junior players couldn't even talk to him—
I used to be skeptical about these stories, but now I'm starting to think they really did happen.
