England have won the World Cup. Liverpool are one of the most successful sides in the history of European football. Yes, both sides have fallen off since and do provide comedic moments. That said, the hype and arrogance thing is completely overplayed. Listen to the England team anthem '3 Lions', its satirises England's hapless fortunes since 66.
Granted that some fans are ridiculous (they are for all countries) and the Sun is an awful publication that shames us but it seems to me that the Home Nations fans channel a general anti-England feeling through our football team, regardless of the actual merit. The Twitter account
@Kostur posted from yesterday showed the more extreme end of the dynamic.
