Don't think anyone is losing their head, but obviously when a player is having a great performance and then is benched the next game you'll see reactions. Doesn't automatically mean that it's the wrong decision.
I’m not against DCL as a player per se, physical presence and someone who can hold the ball up, but obviously it’s the injury record and the fee/salary. As been mentioned, feels like lazy ”scouting”, has to be better value out there.
Reminds me of a clip I saw from training with Ole Gunnar Solskjaer, managing Cardiff I think. He kept shouting "Shoot! Shoot! Shoot! Shoot! You never gonna score if you don't shoot!" Football genius, that one.
