Again, there was nothing wrong with how he behaved. He was NOT dressed in t-shirt and jeans - there is a video on youtube where you can clearly see him wearing black trousers and dark shirt. And if he had his hands in his pockets, that doesn't show disrespect to me. It just shows he doesn't like his arms swinging stupidly at his side.
Fwiw there were scores of Saints fans there in shorts and t-shirts, why didn't they make the effort?
