Manchester city have lost some of the good hands that have made the club the top for several consecutive seasons and also haven't won other leagues aside from champion League that we are discussing here, shortly after the last season the club was opened up to some team management that the clubs could have pay whatever prize to retain and even increase the good hands on the club to put them up alin better position compared to the present position that Manchester city fund themselves this time around and the underperformance is not only in the champion Leagues but all the other leagues that the club in engaged on in this season.
Pep thinks that the players he signed to replace these players he let go can perform to their standard or above their standards, but they couldn't, and the team is becoming unbalance if one or two players get injured especially Rodri. I think things will become better since their main man KDB is back from injury and will soon start playing with the rest of his team mates.
Everything will go back to the way it use to be in the beginning of this season since DKB will join his team to the field soon to add great impact on the club's performance. Manchester city will go far but they might not be able to win UCL this season because there is a change in players and it is not the exact complete squad that won the league last season is still the ones playing as some have been replaced and that has declined the performance of the club a little.
However, if they are determined and improve on their performance, they might be able to win the league but I see a very slim chance for them this time, because the best team will always win the league.
