In the past the recruitment of management and players has been awful. I am not sure there was any noticeable strategy at all. The managerial appointments were pretty random and unfortunately that continued with Rangnick. I think the caf speculated so much about his future involvement, because it didn't make any sense to appoint him "just" as emergency caretaker.
In general, nobody really seems to be certain about, who is making decisions. That makes dodging responsibility really easy.
The optimistic view is, that there seems to be an effort to change some of the personal in the upper echelons. I don't know if Arnold or Murtough are leading this, but its a promising step. The way I see it is, that it has to work and there has to be drastic and immediate improvement. Non of these people have much credit in the bank. At best they have almost no track-record in this capacity and at worst, they were involved in the previous 9 years of failure.
I don't really know ETH, but he is imo the first promising managerial appointment in the post SAF era. If Arnold/Murtough believe that he is the right manager, they have to ensure that he gets all the tools he needs to improve the team. If they think, that the same group of players can turn it around, they'll have to accept the consequences if this strategy fails. This can't be the start of another never-ending rebuilding process, where the club takes one step forward and two steps back.
