At the moment I am not sure Wolves are good enough for Mr Tierney. The comment about confidence is rubbish imho. He had the confidence to ignore a yellow card in order to man manage the game which could have lasted 120 minutes. If Spurs were good enough... That it backfired was unfortunate but the referee gets no plus points if a side goes down to 10 men. I have noted other experienced referees refuse to issue second yellows where they can.
Junior mk1 has never forgiven him for not awarding a penalty to Derby back in the Championship but I have always rated him highly.
