I'm sure he's fully aware about what he's doing but I'm disagreeing with him on this occasion. I doubt Pep will be here for more than five years, I'll be here for the rest of my life. So where Pep doesn't wanna risk playing a youngster in goal because 1 time out 500 that would make us lose this game today, it just shows to everyone in the Academy and young players around the world that we don't like playing our own kids (no kids on the bench today wtf???). It seems that we're learning f*ck all from Sancho and Diaz forcing their way out. And while Pep is the greatest manager in the world he doesn't really care about our Academy players as he'll probably leave us long before they reach their peak.
Edit: Feel this all became a bit messy but hope that I made my point clear at least
