I only watched the highlight once but it looks to me that the player from Belgium trapped his own leg coming from behind the player from Senegal who was in the motion of clearing the ball. Belgium should have just rolled the ball to the goalkeeper and not accepted the penalty. I never understood this side of soccer. If you take a dive to win a free kick then you've cheated. Winning should feel empty. I'm glad they're starting to take wins away even after the fact if a player fakes a foul and fools the ref. With the replay this ref had no excuse for this call.
