Manchester City is not actually bad in terms of squad. I think his backups are also very good, at least for a backup. Even though they did not get exactly the results they wanted in the Premier League this year, I see their future bright. When they get in shape towards the end of the league, they win consecutive victories and continue to be championship favorites.
Manchester City won consecutive titles because they have a very good squad quality, but after Kevin De Bruyne's injury they couldn't fill his void. I don't expect them to sign a player as good as Kevin De Bruyne because he is a world star. However, they need to sign a creative player in the midfield. Jude Bellingham could have been a great signing for them if they were faster than Real Madrid. Even if Kevin De Bruyne recovers and brings Manchester City back to their old days, they need to sign a midfielder because Kevin De Bruyne is 32 years old.
