Manchester City really suffered last season, and to be honest, I wasn’t expecting them to be that bad last season, but unfortunately, they did not perform well last season, and it was so disappointing. Although, as you said, you are right; depending on one single player or two in a squad is really a mess, and I feel like it is among the reasons why Manchester City was affected. I just hope they will get back stronger next season because if Manchester City experiences the same thing as last season, it won’t be funny at all.
Yes, of course, I also hope Manchester City will perform better next season. But judging by the last match against Palermo, Manchester City certainly performed very well, and there's certainly potential for a revival next season. However, it would be even better if Manchester City could bring in strong new players who could certainly strengthen Manchester City's strength.

Of course, if Rodrygo joined Manchester City and left Real Madrid, I think it would definitely strengthen Manchester City's strength and improve Real Madrid's attack. However, I think Rodrygo will have a hard time joining Manchester City because, after all, Rodrygo certainly seems to really enjoy being at Real Madrid, even though he's always under Xabi's radar. And of course, seeing Rodrygo score in the friendly against WSG Tirol will certainly make it difficult for Manchester City to acquire Rodrygo. Hopefully, Pep can train his current players to perform better, even if he doesn't bring in new players.
