It could be wise to take Manchester United out of the picture, in terms of teams that won't qualify in that group, but in my opinion, I can't specifically say that Galatasaray and Bayern Munich will only scale through and take Copenhagen for granted. So for me, both Galatasaray and Copenhagen have an equal chance of qualifying in that group alongside Bayern, regardless of which team is ahead of the other in their group table.
If we talk about opportunities, in fact Manchester United also still has a chance at this time if Manchester United can win the four remaining matches in the group stage. But that is a very small possibility for Manchester United to get it, because in those four matches Manchester United will still meet Bayern Munich, who are currently still unbeaten in Group A. Apart from that, I still have doubts about Copenhagen's performance even though Copenhagen had draw at home to Galatasaray.
