Talking about Manchester City's problems in the Champions League, I don't think they will have any problems because even though KDB was not there before, their dominance was maintained even we can see where in the group phase they can get perfect results with 6 wins without losing in the group phase which proves that their dominance is unstoppable even without the presence of KDB in the squad.
Now the Round of 16 we just need to wait for that and KDB and Haaland will definitely return to them especially the opponent is only Copenhagen which although they are quite troublesome but in terms of strength and experience of course Manchester City is better for now so I am quite confident in the strength that Manchester City has.
On paper, City shouldn't have any serious problems when they play against Copenhagen in the round of 16 of the Champions League. even though the first leg match was held at Copenhagen headquarters, the fact is that these two teams have quite a clear gap. we can refer to the betting market, even though it is temporary, City is far superior even though the match is played at Copenhagen's home ground. I don't know yet whether KDB has fully recovered, played or not, but City still has depth that is far above Copenhagen's level. after all, Pep will be more serious and play his core players in the Champions League. they will target full points, in order to smooth their steps. at least, in the second leg, City will play more relaxed if they beat Copenhagen, especially with a landslide score.
As for Copenhagen, I don't mean to underestimate this team. however, they had quite a difficult time playing their match in the Group A phase. If Bayern had played seriously at that time and targeted full points, perhaps the situation would have been different for Copenhagen. however, despite being an underdog team. However, Copenhagen will work hard when they play their match against Manchester City later. and what's interesting is, after the round of 16 match. in this phase, the match will be more serious because the team that passes certainly has the potential to make it difficult for City to advance to the next stage.
But still, I still have great faith. if City plays its full core of players, and Pep implements his signature pattern. whichever team is the opponent, it will be difficult to match and provide resistance to City in the next meeting. in this phase, the Champions League will be more exciting and tense.
