Presume you mean Pep's ego!!!?
This is silly, I mean I am sure pep failed in some sense there sure, personally I believe the transfer was a bad idea because Zlatan isn't the type of player Pep prefers not to slight Zlatan. The issue here is that you cannot do what Zlatan did, you cannot by any means expect to publicly undermine a coach, much less a Barca and current football god and expect anything less, after that point that was it.
Furthermore, the ego claim is valid for Zlatan as he claims has already openly stated that he could not understand how barca stars were not nearly as egomaniac as what he thinks stars player should be like and that he tried their way but did not fit in saying that was not the real Zlatan. Implying e must act like he is egomaniac self, which I don't mean to knock but if you want to start in the best team in the world then you better recognize it is a team game.
