Pep would have done this or that, while true, is IMO not important because Pep is arguably the best manager of all time, while EtH is at best, a top 10 current manager.
What is concerning is that no name managers of teams with far less resources seem much more able to have their teams play actually decent football, despite not having years of coaching and hundreds of millions in investments. Wolves for example, are a team with players who are much worse than ours, with a manager who was there for a total of 4 days, and somehow completely outplayed us in Old Trafford.
