I feel a little sorry for Rasmus Hojlund, even though he has quite good quality but unfortunately his team mates cannot fully support him, currently United's Manchester United performance is very bad and this happens on all fronts so that quality players like Rasmus Hojlund are not able to do much.
So I think it is very unfair to compare Rasmus Hojlund with Haaland because both players are in different places.
Erling Haaland is a little lucky because he plays in the Manchester City team with full support from his teammates so Erling Haaland can bring out all the abilities he has so that Erling Haaland's true quality can be seen.
Are you sure he's good, I think the stats at Atalanta are not so noticeable. But with the current age, his ability is still very developable. In the last few games of Man United he made goals and that's a pretty good development. So he is not good enough for the time being, although indeed the current condition of the Man United team is indeed not good, but blaming teammates seems unfair to Rasmus Hojlund's current performance.
