The worst one the refs missed was Højlund getting intentionally hit in the head in the penalty area, which should have been a red and a sending off, but VAR didn't intervene because the REF waved it off.
Other than that there were several attempted kicks at Højlund that wasn't called, in one instance he was kicked 3 times befor finally getting a freekick because the ball was lost.
In all honesty it started because Højlund hit a defender with his elbow and fell on him afterwards, which seemed to make San Marino's players see red. It didn't look intentional, but things turned ugly after that, and that was around the 30 minute mark.
For reference Eriksen argued with the San Marino players several times, Kjær too, and those are probably some of the calmest player I've ever seen in football, especially Eriksen. I don't think I've ever seen him argue this much with opponents.
I hope United sign him, I'm not basing this off of two games against them, I'm danish and have seen plenty of him.
He has a lot higher ceiling than Amad, Pellistri and Antony IMO, and we really need to get better at locking down young talent, which we can either continue to develop, or sell on for a profit.
30 mil + add ons is ludicrous though. He would be worth 15+ add ons when looking at recent sales from the Danish league. Kudus went for 9 million euros, and he was twice the player in that league, although he was also a bit older.
