It was not a yellow card, won the ball
BUT if being on a yellow meant he was going to bottle any challenge then he might as well have asked to be substituted. There was no excuse for him not putting a challenge in and then then lack of effort to try and get back
He had a rubbish game BUT he was not alone in that regards
Simpson is a limited player, that much is clear. At best he will put in a decent performance defensively BUT he offers nothing going forward, can't control a ball, can't pass, can't cross, can't take people on etc etc - just long aimless punts, one after another
