I think that it would be more important for Guardiola to win the Champions League again, but they couldn’t beat Real Madrid this time. Of course, winning the Premier League is no less important, in such a strong championship, becoming a champion again is a very impressive result. At first it took a lot of money to assemble such strong players, but now City spend less money on the transfer market than Arsenal, or even Chelsea, but thanks to the fact that the team was assembled correctly from the beginning, this makes it possible to get results over many seasons.
Yeah winning one of the titles is enough to prove that they are one of the best clubs in the world but if Manchester City win both then they are the only best team
Pep Guardiola may still be confident in this squad for next season but I personally think they will face more pressure than previous seasons, some teams that have the potential to pressure them are Chelsea and Arsenal I think these two teams will soon be in a golden era which will prevent Manchester City from winning the Premier League title next season. Several Manchester City players are in the retirement area for example in the defense and midfield areas so Pep cannot rely on them unless Pep prepares replacements by signing several new players. Maybe you still remember how Manchester City played without Kevin De Bruyne, the match looks bad and they missed more points. Well, this situation could happen again when Kevin De Bruyne move or retires.
