This is not entirely correct; Bayern Munich played to win their last match against Copenhagen, but they were simply unlucky due to Copenhagen's defensive mindset. Copenhagen knew it would be difficult to beat Bayern Munich, so they immediately fought for a draw, which they obtained at the end of the game. When they beat Galatasaray in their final group stage match, the one point from this match will give them an advantage on the table and a better chance of qualifying for the knockout stage.
I think Bayern Munich didn't take them serious or it was because they think they are qualified already with the points they have gather even from the short on target, Copenhagen had twice what Bayern Munich had in that game which means that Copenhagen put more to win that match than Bayern Munich did. It's good that they are staying in the second place. The race for the second place is now between Copenhagen and Galatasaray,however I think Copenhagen has more chances because it's their home match.
This is exactly what will happen; Bayern Munich will either win or draw the game. If either of these two outcomes occurs in this match, Manchester United will be eliminated from the Champions League competition, and they will not even be eligible for a Europa League spot if they do not win all three points in the match.
People that are yet to give up on Manchester United are doing false hope. Why didn't Mancj United do all they had when they started the Round 1 group stage, it's now the are praying to win their last match to get 3 points to qualify and Galatasaray with Copenhagen draw, it will not happen. I don't expect that to happen because Bayern has fall off in their last match, they will do anything to avoid control damage against Manchester United, they should try and face their domestic league and try next season.
