1) yeah Juve promoting youth

ask claudio marchisio

2) well yes they are gambles but they are also potential gems, either going to be another denilson or another kaka, swings both ways, but generally speaking Brazilians tend to do well in the Italian league anyways, id probably be a bit more concerned if it was the premiership.
3) if pirlo gets injured we're fucked, but as i said before he was marotta's signing, but Conte has had to change his system slightly to accomodate pirlo. But as i said before we wont actually buy a replacement for pirlo when he leaves/retires, we will simply buy another midfielder that Conte deems best fit for his system which won't necessarily be a deep lying play maker, rather someone who is a all rounder
