The problem with Italy is that they are so archaic and outdated in their treatment of young talents. They want to win immediately, but some of the players starting for some of the big clubs are nowhere near good enough. Look at Milan's midfield, and our attack for example. The top 2 teams in the division have very average players patrolling key positions, whether it be in midfield for Milan, or in attack for us.
Italian clubs can't afford to buy the biggest talents/players out there, and yet they are reluctant to give young promising stars a chance to shine. The end result: Many average players across numerous clubs in Italy.
