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.
Guardiola is a very experienced coach, there is no doubt about it. Even Manchester City's success has come from Guardiola's hands. He has gradually transformed Manchester City into one of the strongest squads in Europe. Manchester City has won every European title with the help of Guardiola. Especially, City has won the Premier League title for four consecutive seasons. At the same time, the team was able to win the Champions League title.
Since Guardiola is the best coach in Manchester City's history, it is unlikely that Manchester City will sack an experienced coach like Guardiola. The team performed very badly in the middle of the last season. However at the end of the season , we saw City's stable performance.
City has bought Reijnders , Cherki and Nouri this season to strengthen the squad. Guardiola must have a different plan for his squad. We can expect to see another strong performance from City next season. However, the competition for the Premier League title next season will be very intense.
