Yup, Doc Sark pretty much summed it all up. In Germany, there are probably 10,000 football fans for every American football fan, and when England march in to Villa Park tonight, to face Holland, I know that when the anthems start playing, I'll feel a sense of pride.
I think the best example of how passionate some fans can get is the 1994 world cup, some Colombians shot one of their players who scored an own goal.
