Pep Guardiola should be mentioned for Manchester City. He is a coach who tactically considers many alternatives. Considering the chemistry between Manchester City players, I think they are still the best team. Chelsea is a team of new players and it will only be understood when the league starts how successful they can be.
I also don't talk about Chelsea too much because they won't be in the Champions League next season. Chelsea can be expected to appear in the 2024-2025 Champions League if Pochettino manages to end his first season in the top 4. Regarding Pep Guardiola, of course not many people want to doubt the ability and technical and tactical qualities that he has as a coach. His Manchester City has really become a frightening club in Europe and so far Pep Guardiola has managed to bring Manchester City as one of the best in Europe.
After Pep Guardiola managed to win first Champions League title for Manchester City, then of course they will be expected to defend that title from next season. The chances are good, but only if Pep can keep Manchester City's form the same or improve it further next season. But imo, the new season is a new challenge and it will never be the same.
