I think Manchester United is gonna wake up and ended up going to the next round, they ahve luck on their side because the other two teams of the group asides of Bayern Munich are weak (Copenaghe and Galatasaray) if that were not the case they can be already more out than in.
For now I can't say Galatasaray is weak because after all, Galatasaray managed to beat Manchester United at Old Trafford. Therefore, in essence Galatasaray cannot be underestimated at all because of course, playing in the Champions League is a big motivation for teams that are not seeded to be able to play well even though the opponent is a seeded team. Indeed, I am also aware that there is still a chance for Manchester United to rise, but considering it seems that the condition and situation of Manchester United is also not very good, it seems that it will still be difficult for Manchester United to qualify for the round of 16. Because of course, to qualify for the round of 16, Manchester United should be able to finish in second place but of course, Galatasaray will also maintain that position throughout this group phase.
