Even if you are right and Mancsher City had a bad performance because of their player Kevin De Bruyne getting injured, I still think they had to have an alternative player in the same level to help the team in this situation and that's not good for a team like Manchester Cty to be dependent to a player like this.
Regardless of that, I'm waiting to see how Manchester City is going to perform in the Champions League after Kevin De Bruyne got recovered when they won't have any reason for the weak performance in the team.
I see other considerations in this case it seems because of course there are priorities that Manchester City needs to pay attention to.
They are well aware that because the situation of the players is not too good because they are too compressed with a busy schedule, their priorities will definitely be a little different.
Indeed, until now we also know what Manchester City EPL performance is like because in the last few matches they have not been too reliable but indeed Manchester City's priorities before must be in the Champions League so in this case im not too worried about what is happening for them especially now that some players like Haaland and KDB have now appeared and participated in training which will certainly provide an improvement for Manchester City
performance.
Pep is quite good at utilizing situations so with the experience he has now and Manchester City current performance i still have no doubts about Manchester City.
