I kept hearing how amazing Sergio Parisse is and how he is the worlds best no.8. I thought it was great Italy has produced such a player. I hear the same about Castro, the worlds best tighthead. Till I find out they both were born and raised in Argentina. I read somewhere 15% of the Italian squad is from Argentina. What do these Argentinians leave Argentina to play for Italy? Imagine how could Argentina would be with all these players.
