There is a better angle that was shown during the live broadcast that goes across the back line. Most of the cremas players are offsides, but the guy who heads it is onsides. Parks LETS HIM GO thinking he is offsides but everyone behind him (Parks) had dropped deeper already. He (33?) heads the ball, and there are 2 players in front of goal. One of these players is offsides and the other looked onsides to me by a bit. Johnson makes the save and the player who is onsides finishes. The offsides player didn't make any attempt.
