Some of you look too much at his stats for this season, but completely forget the background behind them. Højlund joined Atalanta this summer from Sturm Graz, before that he played for FC Copenhagen. So before last summer he has only played in the minor leagues. This season was his first in one of the major European leagues. He spent the autumn getting settled in Italy. He had to learn the language, the style of play and adapt to the level. He has actually managed all that in a fairly short time, if you think about it. He spent an autumn. After that, he started scoring regularly. When things were going very well for him, he was injured. It ruined his good rhythm a little, but he is starting to score goals and play well again.
So there is a story hidden behind the stats, and you can't just look at them. It's too black and white.
He is only 20 years old and has adapted to a big league in a short time. He has also started scoring for the national team (5 goals in the last 2 games). He is a typical number 9 that we really miss. He can head, is fast, is good at finishing, is hardworking and adaptable.
I believe in him if he comes to United. I would not be surprised, if he can already score 15-17 goals in a whole season in the PL.
