Well look at Parma getting promotion in the 80s and winning the UEFA twice in the 90s.
Look at the Italian national team winning the world cup.
Look at the coaches to come from Italy like Capello, Lippi, Mancini etc
Then look at how the English league needs foreign managers to outclass other leagues in the champions league.
In the last two years an Italian manager has won the world cup, an italian manager has won the champions league, an italian manager has won the serie a & an italian manager has won la liga.
A scottish manager won the english league, a portuguese manager won the fa cup & a spanish manager was trying to win them the champions league.
Italy produces the best players and best managers, therefore surely the best football.
Once the crowd trouble get sorted out (and you can do that) what will the English complain about then?
Your style, your talent or your medals?
Forza Italia :-)
