Moyes and Solskjaer were completely out of depth.
Lvg and Jose were top managers and they were logical and good choices but wrongly executed. They needed DoF.
Ten Hag. At that time he was good choice but again DoF problem (in his case awful Dof).
In which universe were Lvg and Jose top managers? Lcg signed players based on world cup because he wasn't even watching lot of league football back then(I seriously doubt he even followed EPL), let alone was top club manager at that time.
Jose is long past it, not even Chelsea wanted him anymore, how on earth was he top manager? I literally argued in the OP that his biggest achievement recently is managing Roma, and you completely ignore that and continue to call him top manager.
I think it's more that anyone good enough to be successful wouldn't have taken the job in the first place with the set up we had.
That's the part that will (hopefully) change now.
Don't really disagree with the opening post. I just think picking the wrong manager comes with the territory when the people above the manager don't have a plan
That's also true. But then many poor run clubs have won many things in between and have signed some shit and some good managers. I don't think Liverpool were much better with their transfers and some decisions than us either, except the main one - hiring Klopp. Barcelona, PSG are shambles and probably worse run club than us, so are Chelsea too, all of them won more than us(I think).
