I don't think that it's because Manchester United was a big team that was why he was not able to deliver the truth is that any player coming to Manchester United will not play at his best because the environment in united is not a good one that players can do well
It's true that any player that comes to Manchester United finds it difficult to perform well, but in the case of Hojlund, I totally disagree with you because Hojlund got so many opportunities he would have used to score goals for Manchester United this season, but he failed to convert those opportunities he had at Manchester United into goals, which caused Manchester United not to win some of their matches this season.
The case of Hojlund is just the with Nicolas Jackson of Chelsea, they both had enough time to improve and prove everyone wrong but they were just reluctant and didn't do anything to improve. Hojlund missed a lot of chances that even some fans at the bar that I watch matches always say that even if Hojlund should be on goal without a goalkeeper he'd still miss. When I heard that I felt bad but then it was just a bitter truth, he seem to miss every chance he has. I wonder how would a striker have such a creative midfielder like Bruno Fernandes and not manage to score at least 15 goals in one season. I know the team as a whole is struggling but Hojlund performance was just so terrible and I am in support if they want to get a new striker. I think Hojlund is an average player that's why he can't thrive at United.
Hojlund has failed to live up to expectations in United because should be let go if United is to make an improvement and leave this current level that they find themselves so letting him go is the better option so that they can use the money for his sale to get good quality striker that will be consistent
