I think you’re making way too much of this perceived ‘love in’ with other managers.
This is just Pep’s stock approach in press conferences - he does it all the time, yet nothing is made of it when we win.
He did exactly the same things with Brendan Rogers the week before - and even more so with Ancelotti in the FA Cup QF - but no one gives a shit because we won.
You’ve picked the only 2 examples where we’ve lost a game this year as if they are the only times he’s done it - when the reality is you could rewatch all the press conferences for 2021 and you’d find exactly the same pattern.
I very much doubt he’s sitting around the CFA all week eulogising to the players about how great the opposition Managers are - but as all we get to see is a half hour press conference every week, you’re assuming that’s all he’s got to say about the teams we’re playing.
Pep very deliberately doesn’t want to get into slanging matches with opposition Managers like Mourinho loves to do, so deliberately gives the press fuck all to feed off.
That’s all it is!
