Yeah, still manager's job is man-management and this may be a public lesson for CHO. All the time we hear this team is hard to motivate and acting like a stars, so maybe it's finally someone to make a call for CHO that after his Bayern BS and all other toxic stuff he has to work double for his high contract, as being good in 5 matches and riding on wonderkid's reputation is not enough. And a psychological tactic that may or not work with young players who are over their heads may not actually work for Werner's or Oli issues. We don't know what's going on in this team, so as someone wrote, let's see what comes out if it.
Plus, I don't really get the drama with players being subbed; Yeah, everyone wants to play, but it's a team sport after all. If some element of team needs to be switched, then well, that's life.
