I really thought EtH was the one. His first season reinforced my view. I still think he is a good coach (Rashford, AWB improved greatly under him last season) but he has a no idea what to do in the transfer market. It reminds me of him sticking up for Ovrermars after the latter's scandal came out. EtH knew how instrumental Overmars was in building the Ajax side. EtH needs a strong guiding hand in the market in the form of a DoF with a coherent vision. Unfortunately we are a relic of the past who just give managers all the power and ask him to do the job of head coach and head scout. It's been that way since SAF, but there is only one SAF. And as a result here we are.
All of the above can and should be majorly attributed to the Glazers. But EtH's biggest failing in my view is abandoning what worked last season and going with a suicidal 4-3-3 with an aging DM as the anchor. It all starts from there. And he isn't changing it either. If he admitted he was wrong after the first few games, the players' confidence wouldn't hit the rock bottom it has now. Now the players have done what they always do and have given up. He'll probably get sacked and I won't be against it. But first and foremost the upper management needs to change for there to be any hope.
