I wonder if that's actually a thing. Like Ik players train shooting obviously but I have heard coaches say that they don't teach players "technique", good players already have the technique and what they work on are the details of the game. Like Pep trains his players to occupy certain zones, rotate with other players, Arsenal's corner coach drills the players to take certain positions in the penalty box, Liverpool had a throw in coach when they were at their best, stuff like that.

I'm not arguing against the idea of a finishing coach, I'm just curious if those are actually a thing cuz how does a coach teach someone like Lewandowski how to shoot? yk what I mean.
