This could be the reason for the club's poor performance but the focus has been on Rodri's injury and City has been busy in the market trying to get a replacement. So if he doesn't get them back on track after some time or when Rodri is back and fit again. Then we can conclude that it's the divorce saga with his wife that's affecting his judgement and the club might be forced to take action.
Manchester City have essentially lost their defensive mentality and they are really bad at defending. PSG pressed quite well throughout the match and this made Manchester City's defense chaotic. I'm not sure it's just about losing Rodri to injury, but there are other factors that have caused them to be so poor this season.
If Rodri returns to play, maybe he can help a lot in the balance of the game. Manchester City are still good at building attacks, but on many occasions they are completely unbalanced when the opposing team attacks on the counter. The defense is so fragile and Manchester City concede so often, so there must be more reasons than just Rodri. The defensive players are not in good condition, they must also be supported by good midfielders.
