No, you are right. The AR should have alerted the referee, stopped the game, consulted the AR as to what had happened and sent the Chelsea player off if that was what he thought was correct.So we're saying that the following is okay?
1. I get 'fouled'.
2. The ref plays advantage
3. I foul someone.
4. It doesn't matter, 'cos the ref's playing advantage
Sorry, that just doesn't make any sense to me.
