It is still too early to pick a team for the upcoming season. All teams want to win the title every season and defend it after becoming champions. PSG is no different. PSG will definitely want to retain the title next season and see themselves as champions. But the rest of the teams will not only want to see them. Rather, they will also participate in this fight and fight for the title. The list of strong teams for the upcoming season will definitely include Barcelona and Real Madrid, along with Liverpool, Arsenal, Bayern Munich and Manchester City. Although City is not in a good position right now, they will definitely bounce back once the season starts.
I agree with you, it's too early to predict which club will win the title next season because this is a competition where every team will likely show what they are capable of. When it comes to the Champions League, even a teams who are struggling in their respective leagues always come at the top, so it will be difficult for anyone to predict who will win. Furthermore, we have not seen each club's performance for next season to judge who will win, because not every team can maintain its winning ways throughout the season.
Manchester City, on the other hand, I believe that the team can only give all they have in the Premier League and will not pose a threat to any Champions League opponents next season. Many people believed that Manchester City would improve once Rodri returned from injury, and Rodri was there when Al Hilal eliminated them from the FIFA Club World Cup, In my opinion, Manchester City deserves a new manager because Guardiola has run out of methods to improve the team.
