I think he's brilliant so far, and has a completely refreshing, honest approach to things. He's right that tactics are meaningless if players aren't running and putting in the effort. I don't think ETH lost the players completely, he was just a poor communicator/tactician and they didn't know what he wanted - I don't think he knew either, really.
The biggest problem is expectation. Every time Man Utd lose it's a nightmare, a media storm, people are looking for explanations and headlines. That needs to be tempered while he gets to know the squad. He'll be able to identify the major areas of improvement needed. A signing or two in January I think would actually help a lot, but it's always tricky.
Our next run of fixtures are tough, we could quite conceivably struggle in most of them, but so would any team - we just have to ride it out. There will no doubt be plenty of idiots spamming memes comparing ETH and Amorim, but he's only been here 5 minutes.
Dan Ashworth will play a big part too, when they identify players to sign, it needs to be done quickly and ruthlessly, no messing about for months on end.
