Manchester United will play their last game in the group and Bayern Munich is not an easy team to beat. Manchester United will win this match and Copenhagen will wait for the Galatasaray match to end in a draw. I guess any other possibility doesn't help them get out of the group. If either Galatasaray or Copenhagen wins the match, Manchester will at best go to the UEL.
Manchester United will face more difficult conditions in the final match in Group A of the Champions League, because Manchester United's potential to qualify for the next round is very slim, as is Manchester United's chance of getting to the Europa League. Because if Manchester United draws or loses with Bayern Munich and Galatasaray or Copenhagen can win their last match in Group A, Manchester United will only have to return to the Premier League without qualifying for the other competitions this season.
