As the manager, the people who work under you don’t have to like you and they don’t have to blindly do whatever you say either, especially if what you’re asking doesn’t work. That’s why it’s called management, you need to manage people otherwise you’ll get fired, and that isn’t because if player power or whatever other cliches you want to throw out, it’s just piss poor management.
And you can complain about players being self interested but what about the managers we’ve had post Fergie? They all only cared about their reputations more than the club or the players. Most of them wanted the entire squad sold at different points because the players didn’t believe in their bullshit systems anymore. Would you run through a brick wall for someone trying to bolster their CV at your expense while they’re failing miserably?
