I dont think that the Italian NT would be better if Juve Milan and Inter were to use only Italian players,or maximum 3stranieri.
Italy has a good system of developing young talents and its not based on foreigners,Italian players value, is sometimes higher than their true value
and they rarely have to leave italy,
world class foreign players add to higher competition,
help to further increase the level of Italian players skill,
young Italians have the chance to learn from the best footballers in the world
and they will have to be competitive enough to match everyone out there or die trying.
Lets have look to clubs that use players only from their countries(Rosenborg,Steaua,Wisla krakow etc etc)what did they get using local players only,are their national teams better?
Compare them with Spanish,French,Greek,Turkish clubs, etc etc
did they get any weaker?did their national teams got any weaker?
There are teams like Palermo,Parma,Lazio,Sampdoria who are powerfull enough and use Italian players only,these are the kind of teams that sould use and promote Italian players and when they are ready,the best of them would (easily)reach players of one of the best european teams,a task much more dif for someone else with similar or even better value would achieve,
try to look from a footballers perspective,see how easy is for a Tacchinardi and a Miccoli to wear the Juve jersey and what adventures,teams,efforts must overcome players like Mutu or Nakata to get the same place,
i dont think the Italians are the ones disadvantaged here...
A big team like Juve sould be complete, competitive comparing to the other best european clubs and set the standards, smaller Italian clubs sould follow.
teams like Juventus is what makes Italians proud,
we are in the top of the world and we use many Italian players
and we fill up the gaps, Italian football cant offer momentary, with elite stranieri,
many of the stars,the coach and the captain of the team is Italian(Buffon,Canna,Zambro,Camo,DP) for the Italian fans to cheer and some foreign key player/tools(Thuram,Neddy,Treze,Emo, the Italian market couldnt provide) to help get the job done and create a formidable group of players.
the key here (as always)is the balance...
