Ive not played centre half for a while but when I'd did the golden rule was to attack the ball facing away from your own goal, not running towards it. At every corner today there was a big gap between the 6 yard box and the edge of the penalty are, which the attackers and defenders both ran into when the ball was delivered. It's no wonder that Cresswell headed into his own net, the ball was bound to go in that direction!
