I also said that not only Man City some other teams like Liverpool Munich Milan PSG and Arsenal are giving a tough time to teams. But lets wait for the starting of UEFA Champions league 2024/25 season.
The next season champion league tournament will be a very tough one then this season due how so many clubs are prepare for the next coming season, apart from the Manchester city there so much teams that are are going to be tough as you mentioned them earlier expecially, a team like arsenal I'm expecting a good outcome from them. Because since there able to win the champion league this season; they want dominate the entire next coming season, and in my view arsenal can make that happen with how they improve their performance better, But nevertheless let us be wait and see what can actually happen in UEFA Champions league we can't make an early predict.
Well this is a common thing as I believe every season the teams do prepare for the next one ahead so I believe there is no special thing about this. The moment the seasons end every team will try as hard and possible as they can to actually make their team stronger and that's what all the teams are doing now, well for Manchester city the market is not yet over so am still open to see a new addition to their squad.
All teams certainly want the best results, but this must also be balanced with their financial strength, where player prices are currently starting to become unreasonable. For big teams, of course they don't have any problems in that regard and they can easily strengthen the depth of their squad. But it also won't run well if you don't have good management.
However, it seems that small teams will still have difficulty competing in the Champions League and again they will be like a minority in big championships. If we talk about Manchester City with their current squad, they are actually still very strong, but sometimes that's not enough if you want to compete for the title again and at least Pep Guardiola knows what his team will need in the future.
