Xavi would probably do a better job to be fair. Man Utd need pragmatism right now and charisma with the players. He brings that.
Ole had the best results of recent, and he was far from a good manger.
While these guys like Amorim and Then Haag were too heroball. With the hero, being them, and the bull, being everyone else.
Xavi failure here more than anything was refusing to build a world class management team to aid him. You would hope that outside of the Barca environment, that he would broaden his coaching team next time around with more experience.
Unless of course he goes back to an Arab team. Of which he will bring his Brother and Co. But Saudi wouldn't be as cushy as before. They want instant gratification and you can be out of a job there as quickly as you are in one.
