Expectations are high for Hojlund. I hope he can play successful matches at Manchester United. High-level performance like Haaland should not be expected. I think he can be considered successful for Manchester United if he performs over 15 goals a year. I agree with what you said about Maguire. He's hurting Manchester United now.
He is quite young and he will be having lot of pressure on him especially after being bought by a big club like United for a big price tag. He will be on spotlight so if he performs well in his starting matches then he really will have great career ahead. So it is really important for manager also to make him comfortable as much as they can. Even Haaland took some time to adjust so Hojlund will need as well, it's same for everybody.
