I wasn't even looking for his knee. It was clear his elbow was down before the ball crossed the goal line. And in order for him to lunge forward after hitting the ground short of the goal line, he would have had to push off from somewhere, and that somewhere definitely was not his feet.
That's a good point. Obviously the refs got it wrong, if there is some governing body they should be reprimanded for f_cking up such a big call in such a big game.
