Yes, it's not over for Manchester United, but what is the percentage for Manchester United to beat Bayern Munich to open up a chance of qualifying? I think it's very small even though they can win against Bayern Munich but their fate will still be determined by the result of the Copenhagen vs Galatasaray match, so Manchester United fans have to be realistic and accept if they are eliminated and that would be good so they can focus more on the English Premier League.
Manchester United doesn't stand a chance against Bayern Munich because the way they have been playing lately is nothing compared to Bayern Munich performance because even considering there last meeting, Bayern Munich was able to beat them so there is every possibility that Bayern Munich is still going to beat them again on there next meeting so I don't think Manchester United stands a chance of qualifying from there group although if it was clubs like Galatasaray or Copenhagen I would have said there is a possibility of qualifying, but to win Bayern Munich I don't think is possible for them.
However for the second I'm seeing Copenhagen qualifying because they have a high chance of wining Galatasaray and also considering were they are on there group table.
