Those are not the rules though. You are "allowed" to hurt other players in football. You might even get a free kick for kicking someone in the face.
These are the kind of incidents where VAR isn't useful i nmy opinion. There will never be agreement on this. I haven't checked deeply, but I'm certain you will find high profiled refs on both sides here. One of the most well known refs in Norway said he didn't think it was red. I have no doubt many will think it was. I also think it highlights a problem with VAR. I believe the first picture the ref sees is a still picture of the impact - which is brutal - but in my opinion is also misleading as to what actually happened (when it comes to determining blame). A bit similar to showing a picture of an aerial duel where someone's elbow touches someone else's face. From the picture, you cannot tell if that is an infraction or not. I guess we need legal experts in those VAR rooms.
The kind of situation we saw yesterday isn't that uncommon. People will accidentally hit other players, but very rarely do we see the kind of impact we saw yesterday. I think it is very difficult to argue that he intentionally hits the Ukrainian. Now you don't need intent for it to be red - recklessness is enough, but if he hits him on the side of the leg and it "brushes" off - then I don't think anyone would have considered that a red card.
I get why it was given, so I don't have a problem with it - even if I don't think it should have been a red. I also think it was quite close to a 50/50 game (Sweden slightly better). "Random" events will typically decide games like that - especially in tournaments with extra time. Some other time it will benefit Sweden.
