The ref would have had the final say without VAR and he wouldn't have given a card at all. Also, I was watching the video being played to the ref, it looked like it was one selected angle out of context of the rest of the shenanigins from the defender, who decides that?
Not only that, the ref being shown something he has missed is in an immediate situation where (From his pov) everyone else has seen something he hasnt, puts too much pressure on him to make a decision. Lastly, who decided that was a clear mistake from the ref? Because thats the implication with VARS
If they were playing Russia last night all of those questions would have been asked imo. Russia being dodgy like.
