Many Man City fans and bettors are furious with the team's performances this season. Compared to last season, Guardiola's team has experienced a significant decline in performance. While I won't blame any particular party, Haaland and some other players, like KDB, declining performance suggests that Man City's management will need to regenerate next season.
I think Pep understood all the problems of the team a long time ago, just decided to change the team, tactics and so on in the new season, because this season was roughly speaking lost in advance, they realised that the chances of taking a trophy are not much. Besides, he himself said that KDB is not in the right shape and can't help the team as much as he used to, so he is leaving the team and most likely will move to Italy.
