He can't. He knows he made a mistake but he's already awarded the goal.He hasn't resumed play, why doesn't he just call it offside now?!?!?
Mexico need to dive in the box if the ref has any conscience he'll award a penalty.
What happened to the extra officials on the goal lines?
They were there in Europa League and Champions League...if they had them here the England goal would have counted and that goal would not.
