Exactly, Manchester City is not an appropriate opponent for Copenhagen especially now that Manchester City will played with a full squad because Kevin de Bruyne has recovered from injury so we will see a different game from Manchester City or we can call it Real Manchester City and I will say it's an easy win for Manchester City. This match will be played in February and there are still many moments to be passed but if Manchester City plays with the main squad then it doesn't have a way for Copenhagen to get points/win.
Copenhagen is not a tough opponent for Manchester City, but it is also very important not to underestimate any opponent when any team starts competing again in the Champions League. Because here all teams will use any strategy to win and those who underestimate their opponents will usually not get anything, so it is very important for Manchester City to play well even though their opponent is Copenhagen because from that opponent Manchester City can advance to the next round. if you are able to win with a good enough score.
