Macnshter City is currently in their best form in which they can have the chance to win the title even in the next season, if you ask me, I think Macnshter City is still the first hope for the next champions league. They still have a coach like Guardiola in their teams most of the important players they have like Haaland are in the best form. That's why I believe Guardiola and his players can even win the title for another time.
You have a point, but we can't say they'll win the Champions League for the second time in a row. Your point was based on their final performance of the season. We must wait for the next season to begin before we can rate and conclude on each team's performance and how they will farewell in the Champions League when it begins.
But keep in mind that Pep Guardiola is an adventurous person, so there is always a possibility he will leave especially according to his statements if the club he loves calls, nothing can stop him from leaving and that club is Barcelona. Pep Guardiola will always be adventurous looking for new experiences, add insight and revive clubs that really need his services. Even though at this time Man City is comfortable with the presence of Pep Guardiola, it is likely that his departure will leave many gaps.
Building a solid team is not an easy task, as Pep Guardiola demonstrated with Manchester City. If they don't have a capable manager to take over after he leaves his job, all of his hard work in building a strong Manchester City will be for naught. Pep, in my opinion, should try a new club he hasn't coached before, or even a team in a league he hasn't managed any club before; his adventurous perspective seeking new experiences will be more entertaining to follow.
