He told ZOO magazine: "I was in the stands for our 2-1 win at Wigan, near the end of the season. They scored first and their fans were turning round and giving it this and that towards me.
"Then we scored and I was the loudest person in the directors' box. I turned to Darren Fletcher next to me and said, 'If they score again, I'm in trouble'.
"After our winner I left straight away. I had to because if I'd gone nuts and they scored again, I'd have been so embarrassed. I drove home, kept the radio off and texted a mate to see if we'd won.
"I'm a bad watcher, a bad loser... the lot."
