How do any manager applies to any job? I thought they get called or something
Well, many of them (most of them?) have agents,
who you'd expect to be offering their clients to clubs.
I wouldn't be surprised if agents, via their connections or whatnot, know before we peasants do, that club X is considering replacing managers for whatever reasons. And then they can maybe step in and offer the club to consider a manager they otherwise wouldn't have thought of?
It's hard to imagine that managers' agents are only there to negotiate contracts after some club calls the manager.
But yeah, the part about applying for a job is a weird one.
do you send a club that already has a manager a presentation of your ideas as a manager,
and get an email that they've saved it and will get back to you if it was ever relevant?
