After the Manchester Derby, Mancity probably will rest some of their key players against København due the crucial match against Liverpool 3 days after this match.
Mancity maybe only win with 1 goal difference, I dont think we will see a spectacular result in this 1st leg.
There is a 2nd leg if Mancity fail to win against København and with the Mancity 1st team, Im sure they able to win at København home.
But if they lose against Liverpool = it will be very hard for them to win the Premier League this season.
If Man City loses to Liverpool, it won't be that big of a difference in points. There are still other matches to chase points. Man City wants to repeat their success last season. I don't think there will be any reason to rest their best squad. at least they will ensure superiority and will replace players to maintain the squad's fitness.
Man City's next few matches will be quite important. they feel they are facing quite strong teams. they have to prepare many fighting strategies.
