To your latter point, check out this (credit to Fox Soccer): Between 1989 and 1998, nine of the 10 Champions League and European Cup finals involved Italian teams, with four winners in that time. Of the seven UEFA Cup finals from 1989 to 1995, six were won by Italian teams, and a total of 14 Serie A representatives featured in the final between 1989 and 1999.I'm not sure how enticing Columbus or Denver etc. are to Europeans. Of course money talks but I'd think New York City and Toronto themselves being world class cities help. (Add L.A., Montreal especially for French speakers and a few others to that list)
Crazy though when I first started with watching European Football Serie A was THE destination. The Prem was up and coming and La Liga was good but Italy was clearly the class league of the world. Come a long way down in a relatively short time.
