Iqbal hasn't played that much for Utrecht because of injuries, and the frustration was by the fact that ETH blocked his loan but almost didn't use him at all, then sell him the year after. I think it's reasonable. Obviously there are some people that will overhype him, that happens to almost every player.
For Hansen, he was blocked from playing on U19s Euro just for a few min in one pre-season game, then was kept at the club somewhat after the summer despite 0 plan to integrate him to the seniors. I mean if you don't think he has it in him to play for United senior team at the first place, why even doing this? Just loan him out or even sell. This half-ass ambiguous stuff is what frustrated the players and people around him.
He has gone up at least one-two gear in his performances for the U21s this season, which more or less invalidate the (previously valid) claim that he didn't impact games enough. That makes things more annoying.
You might have your own opinion on the player's level and potential, but I don't think this is the right management regardless.
I rate him and hope he goes on to fulfill his potential. Maybe Ajax is a good club for him (no idea if the interest is real though). Always have zero expectation for him to make it at United either way, we just don't play with this type of player in the first team. No idea why even bothered to recruit him at the first place. Angel was a better talent and couldn't crack it here as well. It's not like Hansen even developed badly at the club.
