I think Manchester United still has a chance if Manchester United is able to use home advantage well, Bayern Munich is the strongest rival in the group and Erik Ten Hag must be able to create a strategy by keeping Manchester United defense tight so they don't concede goals. To be honest, I don't really like goalkeepers onana because onana looks very easy to concede, I hope Erik Ten Hag doesn't use onana in this match, on Matchday 5 yesterday Bayern Munich was held to a draw by Copenhagen without a goal at home and in Bayern Munich away match later I hope Manchester United will be able to appear surprising.
There is still hope for everyone to qualify for this group, only Bayern Munich is certain to progress to the next round. However, I see that only Man United has a harder time qualifying in this group because their opponent is Bayern Munich and for me Bayern Munich is not an easy opponent even though in the 5th match yesterday they drew against Copenhagen. In fact, this draw will be a special motivation for Bayern Munich to chase three points in the closing match of Group A with 16 points.
Onana is actually good if his defender is also good, I don't blame Onana alone for Man United's conceding. But this is ETH's job to prepare defenders to remain solid and strong in Man United's defense. My prediction in this group that will accompany Bayern Munich to the top 16 is Galatasaray.
