From what I've seen of him, Hojlund looks an outstanding young protect. His main problem at the moment is his 2 wingers (assuming it's Rashford and Antony), are incredibly self-indulgent and wasteful, and cut inside all the time trying (and usually failing) to take their own shots, rather than trying to feed their centre forward.
In fairness, Bruno will try to provide service to him, but Bruno's problem is he's very wasteful too, he'll give the ball away 9 times out of 10. Hojlund just has to hope that the 1 out of 10 times Bruno's pass comes off it will result in a chance for him.
An interesting vignette in the 2nd half v Copenhagen was Garnacho getting to the byline and zipping a low left footed ball across the face of the goal. Hojlund was stood back on the penalty spot and admonished Garnacho for not pulling it back. As a CF, Hojlund needs to get himself in the 6 yard box in those scenarios, but in many ways I can't blame him because he's probably not used to a United wide man zipping in crosses first time!
