Sign or not sign also cause controversy
He's a great player, great coach, but it doesn't mean he doesn't have weaknesses as a human being. Some people think Guardiola is God. He is not: he eats, he shits and sometime acts like a douche like the rest of the world. What was wrong with signing Barca shirt? Is not like you are signing a contract or marriage certificate?
He has signed Barca shirts before. Didn't do one now, but who the fuck cares? No big deal. Pep has done more for the club than most have in the history of it.
Edit: Btw, this guy said it was his shirt and that he did sign the shirt, but shaked his head when he asked for a photo
