Yeah a big issue with discussing Pep is that when people say he got something wrong they usually don't know (or attempt to know) why he did it in the first place.
I'd wager the vast majority of people who weren't happy about neither Rodri or Fernandinho starting the CL final (which is a reasonable thing to feel) couldn't tell you why Pep did it.
Agree mate and also there's the fact that football has an element of luck to it, whatever happens.
Stones slipped in the first five minutes and if Lakaku had hit it they could well have gone 1-0 up and ended up winning the game. This forum would have been chock a bloc full of people saying Pep "Got it wrong" picking Stones.
Mahrez was inches from equalising in Porto and we would probably have won the cup. If that had happened literally nobody would have said Pep "got it wrong".
Managers make hundreds of decisions, big and small, every single day. They ar e not all "right" or "wrong", they are just decisions. Whether to rest, What drills to do today, who to bollock, who to take aside and encourage, who to leave out, who to pick, where to play them, what to say in the dressing room, what subs to make, It's the sum total of those decisions and their implications which make a manager great( or shit, or average). Pep is unquestionably great because he exercise good judgement overall.
There could be all sorts of reasons why he picked that team in Porto. He could have wanted to strangle the life out of Chelsea like we have done at Stamford Bridge. He could have fallen out with Rodri (who made a massive error in the semi final), he could have though Rodri was cocky or suffers from nerves, he worried about Fernandinho's mobility, he could have been too keen to shoehorn what he saw as our "key" players in the team, it could have been a combination of those things. We'll probably never know. But what I can say 100% is that he has more than enough credit in the bank with me to respect and support that decision, even in retrospect, and not to reduce that game to a binary statement that "he had a brainfart".
