We've got a Head Coach for the training, Johnson. We are told that he is a top young coach, I leave that for others to decide. So leave him on the training ground to coach.
Now get an experienced Team Manager to run the team and decide on tactics before and during games. Pop the Head Coach in the stands to take notes.
At present, it seems to me that Mr Johnson, surrounded by even less experienced assistants, is out manoeuvred in games by experienced managers and does not appear to learn any lessons. At this level, almost all the managers are experienced.
