In my opinion this was a decision that was made too late. Now hiring a new coach will make Manchester United spend a lot of money. They will have to pay ETH, they will also have to pay money for a new coach and also the new coach will spend money on new signings, definitely the Manchester United board should have fired ETH at the end of last season I am reading that there are 10 possible coaches that the Manchester United board can hire:
1 - Xavi (former Barcelona coach)
2 - Graham Potter
3 - Maximiliano Alegre
4 - Edin Terzic
5 - Rdi Garcia
6 - Roger Schmidt (former Benfica coach)
7 - Sergio Conceicao (former FC Porto coach)
8 - Sarri
9 - Niko Kovac
10 - Joachim Low
No matter which coach the Manchester United board chooses, they will not be able to make the team champions this season and next season.
You’ll keep on saying the decision made was actually late, the only thing that the club did which was bad in my opinion was to agree to a new deal for him when he was under fire, but keeping him was never a wrong decision although a tricky one, they did their survey and found no manager better than him and on that list you have there there is no one better than him Although this change was definitely inevitable as it is needed now.
Most of the coaches you listed there are not even coming to united is just the media spreading the rumors, only Xavi was rightly contacted, the other clear candidates are Sporting Lisbon head coach, Julien Neglsmann and Solkjaer the former manager
