I think the psychological factor of going to Barca and having to be subservient to a point where you lose yourself as an individual was rarely spoken of during their true peak. It's not every day you go to a club where three all-time greats are plying their trade alongside you, and as good as you are, you're not better than them.
Every time you do something wrong (not pass to them) and mess up, you're getting daggers from the whole stadium and your team-mates, even if not from those three directly. After a while, you're going to become automaton if you don't get the hell out of those conditions as you're pretty much only there to supplement their legacy unless you yourself are at an ATG level and can stand par with them.
I agree about Enrique vis-a-vis Pep for Saurez. The levels of expression and freedom he's currently granted would not be there under Pep's suffocating era.
To a lesser extent, the same happens at Real with so many attackers basically sacrificing their own legacy to make Ronaldo's greater. You've got to have a particular mindset to put up with that, I think.
