Hi I wanted to tell you that it has happened that I have created a league to play with my friends ... as soon as I made a lot of people of all nationalities have come to be entertained ... I ask you, therefore, to make me the boss 400 coins or to give me the option to delete managers
Unfortunately we can't do that.
All leagues are already closed at startup, so you probably opent the league yourself and those managers have every right to join a league that's open.
You can only remove them when they are inactive.
