Meh, it was easy to get carried away. Living in it there was a wave of optimism and delirium, he got caught up.
That said, the world war comments were laughable. I think he needs to educate himself or get his words out better. Some English people do still look back and have this banter with the Germans over the world wars, in the sporting arena, but it's nowhere near as literal as what he suggested. I don't think having national pride is a bad thing, but what he suggested is pure jingoism.
He's not a bad guy at all, there are far worse people around the England set up and analyst base.
