The whole pre and post match by managers is a media creation set up to create content . The media knows they get more engagement with personalities and controversy and the clubs signed up often throwing their managers to the wolves when they've lost a few games and are thinking of getting rid ( Conte, Tuchul, Potter ) . It's like watching the beheading of a king .
Some managers love it and become media darlings ( Klippity Klop , Sean Dyche, Harry Redknapp ) some play with it having studied it from the sidelines (Mourhino ) some intimidate( Pisscan) but most crumble when the going gets tough . In his final year Klopp looked and spoke like a broken man , baseball cap blocking eye contact , and this despite the fawning questions .
As for Pep I simply don't know his he keeps a lid on it . Ten years of unmatched success and single handedly changing the way football is played and the lack of respect is off the scale . None of them deserve to lick his boots .
But to your point about trying to get him to crack ....it's probably true but not a chance of it working. Pep is using the platform , like many before him to galvanised the team . He knows what he is doing .
