Pep Guardiola is one of the best managers ever, and certainly a top name of who we have right now. So that means, we need to realize, he will figure out a way to win again. Not saying he will, but you can never count him out, that dude finds a way to get the wins he needs, one way or another.
I understand the need to actually look like you are going to win, because most teams look like they are great even before the season starts and City doesn't look like that at the moment, but that doesn't mean we are going to see them fail. Pep is the greatest coach by results, the titles he won proves that, treble with Barcelona, treble with city, he is really a great coach and can do so well, so we can safely assume dude has what it takes to get the win again.
