The KFA's authority has been completely undermined, and that is the problem now

Under normal circumstances, the '96-born players should be facing disciplinary action first for violating their duty to maintain professional dignity.
They are practically half-threatening the federation to change the captain by bringing up retirement.
It is a complete mess, yet the KFA is begging them not to retire, which is why their authority has hit rock bottom.
Chung Mong-gyu and Hong Myung-bo are definitely problematic, but fans have completely stripped the KFA of its power by painting it as a villain.
Now, whenever they try to take action, they have degenerated into a group that has to walk on eggshells around fandoms that coddle the players.
In a match, if a fight breaks out, the referee intervenes to stop it, but right now, the national team has no mediator to stop the fighting.
You can just consider it a total wreck.
