I have been working grass roots soccer for the past few years and I had a genuine question watching last nights World Cup game, I was always taught that if a coach withholds the ball form the other team during the rest of play that it was a red card worthy offense, but it seemed to only receive a yellow card, I could totally understand form a game management point of view not wanting to give a coach a red card like that in a game like this, but after a red card just given to the US player it would seem a little hypocritical, at least why was their no VAR review of the coaches conduct? Genuinely wondering if I have this rule wrong or if I just missed something
