to keep the nationalist fans appeased...
Why is this even an issue or considered a negative?
This is a major reason why Juventus has so many fans on the continent and abroad... or do you think it's built on arab/indian (no offense) glory hunters?
If Italy has a bad generation of players, then they will suffer (as they should) as Bayern would also if Germany couldn't produce.
But true suicide would be throwing away the ItalJuve connection because half the fans (tv rights $) are from the south and if those teams continue to grow, then what reason is left to support Juventus? You can then guarantee Juve will become the next Nottingham Forest.
