Honestly, personally I'm not sure Manachester United will be able to win this match, but I also don't rule out the opportunity for them to win this match. If we look at their meeting record, Manchester United have difficulty winning when dealing with this club, I noted from 6 matches they have played, Manchester United can only win 1 time, draw 1 time and the rest they feel defeat. Maybe it was a little luck for them because this time Bayern Munich was more comfortable and there was no burden in this match, but still with a record of meetings like that I can't say with confidence that they will be able to win in this match,
The best result Manchester united can get is a draw from Bayern Munich. The German Giant aren't a team that shows mercy to another team, Barcelona can testify to that, in as much as Bayern Munich has qualified as the group leaders they would still want to make a statement and beating Manchester united is a big statement so the best result for Manchester united is probably a draw.
Yes, it's probably for the best, but with that result, it is certain that they will not be able to advance to the next round. If that happens they also still have a chance to go to the Europa League provided that the Galatasaray and Copenhagen matches can beat each other at least with a difference of 2 goals. However, I hope they do not despair, because after all the opportunity is still there and they must be maximized in this match. They can rely on luck too, hopefully the goddess of fortune will be on their side in this group stage.
