although several players have been confirmed to leave the Man City squad, their team does have enough good quality players to be consistent this season both in the domestic league and in the Champions League. but I feel that Man City's competitors in the Champions League are not Munich, they are still struggling up front. Man City's competitors might as well be from the Premier League. maybe Arsenal or United. these two teams are quite ready to compete this season.
Which player? Kyle and Silva already confirmed stay in manchester city this year. I think that city is only willing non beneficial player like cancelo. Barcelona has been linked to him but no answer from manchester city. All the elite clubs gonna be competitors for manchester city in UCL.
We will have some new fresh name like newcastle. I don't even think arsenal will able to go to the last 16. Arsenal was always showing poor performance when it came to the european competition like UCL.
Arsenal was getting win streak in EPL last season but it's easily kicked out from UEL last season against a mediocre club. Arsenal has been buying some expensive players from chelsea and westham. It's not giving guarantee if arsenal's will able to compete with some powerful clubs in UCL.
The performance from united and arsenal are still questionable at this moment. The opening match of EPL has not yet commenced. We don't know how good arsenal and MU right now in the real match.
