There is alway a guy who can get in my comp while i put in on private. It's already the second season that he can do this. I pay 120 boss points for playing with my friends and than can get a random guy in my comp.
@Beckham-8303 Hi, welcome.
That's only possible if you continue your league, because that's a manager from previous season.
He was allowed in your previous, so he's also allowed if you continue.
The only way to avoid that is to disontinue your league and create a new private league.
