Jose should have absolutely been sacked. He was toxic. There's a reason why no one is atm want him.
Honestly with Jose I think plenty of clubs are interested, and I think he will take the Real Madrid job, or the Barcelona job (one of the two) when there's a vacant managers position, or he will take over Bayern or a german club eventually.
We can all say Jose was toxic because of how he acted towards the end, but honestly any manager who clearly knows in his experience the club needs defenders, and Woordward says no. A manager of Joses experience knowing that, different managers display it in different ways.
He was a world class coach coming to the club, his record speaks for itself, he wont the Europa League, came in a very good position in the league at, with a squad still in rebuild, and then he doesn't get the players he needs and the whole team changes, its the ineptitude of the board that lead to that.
The fact is, Jose was right about what the club needed, he attracted big players, Ibrahimovic, Sanchez, Pogba. Right now you have some like Ole with very little experience, out of his depth.
I doubt Jose would have displayed what he did, if he was backed, he looked angry at the club for not listening, and this year its still not better. I would place a bet on Jose going to a big club when a manager position is free, and he will be the same Jose as he was years ago winning leagues.
Ole isnt right for the club, and United are now competing against Real Madrid, and Barca for a manager, and sadly now... whoever comes into the United job needs to wait for Guardiola and Klopp to leave to even stand a chance at winning the league.
