Yes, and this is why pinning bad transfers on Solskjær and Ten Hag both (and Mourinho, Van Gaal and Moyes, and now Amorim) is missing the target. Both Ten Hag and Solskjær said, and would say, that doing background checks on players characters and mentality was incredibly important. Their task should be to profile the right charachteristics of a player. It’s the task of others to check up on players, scout, and make sure a player actually fits the description. A manager or head coach can no longer do that job, it would be stupid to hand that task to a manager. A manager will describe his needs, and when the scouting team and sporting director/DoF/similar agrees a certain player actually has the mentality and capcities Solskjær and Ten Hag asks for, they should still agree based on their impression that the player fits, or the others will have misunderstood the profile, but he has to trust them to have done the digging and checking well enough.
None of our managers since Ferguson would probably be particularily good as Heads of scouting or even DoF’s, it’s not their skill set. However, no DoF or famed HoS would do any better job of it if they where forced to skip the hours of watching videotapes, reading data and doing interviews were sacrificed in order to be on the training ground and on picking the strategy for next sunday’s game.
If anyone let Solskjær or Ten Hag have players they liked, without digging deep to find out wether they where the prospects they looked, it’s primarily on them and the people responsible for using their knowledge (Woodward, Arnold/Murtaugh and Joel Glazer, I’m looking at you).
