This match promises to be an exciting one between the top and the second team in Group A. If Galatasaray can defeat Bayern, and Manchester United loses to Copenhagen, this group's situation will become extremely interesting. It will become a three-horse race, and Bayern could be at risk of elimination if they're not careful against Galatasaray and Copenhagen. As for Manchester United, I believe they won't have much of a chance.
Even Bayern Munich lose against Galatasaray, I believe they can still at least finish at 2rd position since there's no way they will not qualify for quarter final. While Manchester United has a high chance to stay in bottom and not get anything.
Casemiro is suspended in the next match and there are few good defenders are still injured, Copenhagen should able to win.
