The truth is I don't know how the MU allowed itself to be fooled by ETH at that time, however as I said before, for me he was the destroyer of the MU, and he caused so much damage that the team still hasn't been able to lift its head up, it's difficult to lift a team when it's like this, however for me Amorim has done what he could, what I didn't like was his treatment of Garnacho, it's not the way he did it, but those are very internal problems.
It's hard to get back on your feet when you're in this state, but i think he did his best.
this kind of treatment has not been corrected, but these are very complex internal problems
Unfortunately teams are made up of people and people tend not to get along in an "initial" phase called "storming"
