I grabbed your point. Manchester United might struggle to reach the last 16 of the Uefa Champions League and they might knock out Bayern Munich in a quarter or semi-finals If they meet. Bayern Munich should stop them from qualifying for the knockout stage of the Uefa Champions League since Manchester United is a threat.
Bayern Munich will destroy Manchester United in old Trafford. Manchester United will be desperate for a win and they will be coming so fast at Bayern Munich and Bayern will be waiting for them on the counter attack. Man United and Bayern has a history and they will give their best to make sure they don't disappoint. Even if miracle happens and Man United win Bayern Munich, they will still need a miracle to qualify as I don't see a draw in the game between Copenhagen and Galatasary.
I don't think that Bayern Munich can destroy Manchester United in the sixth match at Old Trafford because Manchester United, when playing at the Allianz Stadium, managed to provide quite tough resistance to Bayern Munich and there was even a chance for them to get points but the home team managed to keep their lead until the victory belonged to Bayern. and at Old Trafford the home team will have a chance to win because there is a prediction that Bayern Munich will not play with their main strength because they have already guaranteed themselves to qualify, but their struggle will be in vain because Galasataray or Copenhagen have a better chance of qualifying if one of them manages to win.
