He can't get a tune out of better squads than ours anymore, so there's no reason to think he can do anything with this one.
He did get a tune out of them. United we’re winning trophies and 2nd, and Spurs were top of the league for a while playing devastating counterattacking football and made the league cup final.
Both of those tenures fell apart because both fan bases had some over entities view of what their football should look like, backed up by a kopite media who hate him, and both had petulant squads full of egos who basically wanted themselves to have the glory not the manager.
Now whilst we have one of the worst most unprofessional squads in the league, we’re relatively devoid of egos with our best players (Richarlison DCL Gray Doucoure Mina) actually working pretty well for any manager. It’s the bottom feeders of the squad who refuse to follow instructions and they’d have no leg to stand on with the media or the fan base if they ignored Mourinho. The board wouldn’t have an issue with anything he was doing. So it would just be down to the fan base to show that it’s not a ridiculous one like United or Spurs.
At Chelsea and Inter when the players followed his methods and the board supported him he got brilliant results. Same at Madrid also.
