All players are different though with how they react to coaches. Some enjoy having an arm on their shoulder while others just like being driven by what’s happening on the pitch. He’s their coach not their dad, so I don’t see it as big deal if he doesn’t quite have a personal relationship with them.
I remember Carragher and Gerrard saying Benitez was cold as shit but it didn’t stop them performing for him. Wenger was a dad to his players especially in the second half of his tenure and ended up with the most mentally fragile team I’ve ever seen.
Morale has been decent for a while now even despite the collapse last season, so you have to think whatever his personal skills are he’s still getting a tune out of them. Plus I wouldn’t use All or Nothing to draw conclusions from, there’s hours and hours of footage we’ll never see, footage that probably includes plenty of player interaction that was too dull to make the edit.
