As an 8 year old in 1966 I remember there was a great deal of satisfaction in the country when England won, but nothing like the euphoria that I think would erupt if they won it now. It would seem like a miracle and all the players would get knighthoods for a start.
No, the mood was more that it was only right and proper that we had won because we had invented the game after all. Plus we were playing (West) Germany and we always beat the Germans, didn't we? That was also said when we played them again in 1970. Those words have come back to bite us ever since.
As this is a pedantry thread, we could get into a discussion on the use of the word "substitute" in football.
