I remember there were several players who deliberately did not play at their best because they didn't like the coach. They played so badly that the coach was sacked for poor performance, it worked and I really wonder if that scenario was thought of by a handful of Manchester United players?
In this situation the manager still has to be sacked cause they have lost control of the dressing room already. Managers have a role to keep the team playing in synergy and all players playing to their top potential, if they cannot do that, the owners cannot change the entire squad cause of the coach and will opt to change the manager instead and remove one or two problematic players.

Some players are very stubborn despite their talents they are very bad examples to the dressing room, back in the days the best manager to handle such players was Sir Alex Ferguson. He was not a respecter of status or class. He had axed lots of top player that were toxic for the team.
Right now Pep Guardiola is such coach we have seen what he did with cancelo. I believe every coach should know when a player is bringing bad energy into his team and when to cut them off immediately before the player influences other players.
