It is very possible, but Manchester United still has the time to put things right, though it is going to be quite difficult. Their fate would be decided in their next two UCL games which is against Copenhaegan, both home and away, if they can win both matches, then they'd be back in contention to make it to the RO16. Manchester United are in a really tough group and i am not sure they understood how tough the group would be after the draw was made.

Erik Ten Hag is under so much pressure, the hierarchy at Manchester United would definitely give him time, but he'll be forcing their hand into a change if the club continues to lose football matches, a club like Manchester United shouldn't be struggling the way they are doing right now.
