We’ve been duped into thinking a manager fixes the problem. At least, some have. It’s as you say. Managers like Klopp and Guardiola aren’t also genius scouts who know every player in the world who fits their precise style of play. It works because they have a competent scouting department which they work together with.
When you boil it down, to succeed you need a manager who has a strategy and philosophy in how the team play. And therefore, identify thematically the types of players he needs which can’t be executed by the current playing staff. Then, a scouting department who is able to identify players within the directive of the manager. Then, a competent “front office” who is able to deliver those targets. And finally, coaches who support the manager in turning those players once acquired into players who understand the tactics and fit the system. Oh, and money to spend (which I genuinely don’t think is an issue) and other things such as quality of facilities which isn’t pertinent to this point, and other such stuff.
ETH may or may not provide the bits he’s meant to. Point is it’s way to early to know, but ultimately irrelevant because we pretty much lack all other aspects of the requirements to succeed.
The fact we target players he knows really shows our scouting team doesn’t have a “list” of targets who might fill the roles he needs players for. The fact we fail to consistently deliver targets represents a failure in those going the deals to either execute them, or if not, identify early enough they won’t work and hence to look for other options. The players we have are also crap but a function of these two issues ultimately.
Until we fix all of these aspects, which by the way will never happen immediately and will take several years, it doesn’t matter who we sign. It doesn’t matter who manages them. And it doesn’t matter who coaches them.
We can, and should, still be able to assess how well ETH manages this group, but it’s like critically trying to assess how many runs a batsmen scores with a walking stick. In the grand scheme of things it’s irrelevant. The only thing we should be (somehow) trying to assess is how well and how clear his strategy is such that it could be conveyed to scouts for them to find the right players.
