aod1984 is right though.
We have been forced to depend on our youth system since our demotion. That's why I have always thought of serie B as a blessing in disguise. If we hadn't gotten demoted, players like Giovinco and Marchisio would have never made it into our super star squad. Our young players would have never gotten the chance to shine.
You can call it destiny, or you can just call it luck but Juve have never had a youth system quite as good as the one we have now. I think in years to come, it's going to prove to be crucial for us.
Very few big teams have this youth system. It's usually the lesser teams that tend to depend on youth systems. They produce stars and sell them to big teams. Parma is a team that has been famous for these actions. Juve can actually maintain these great youth talents because we aren't in desperate need for the money. While Parma had to sell them because they on the other hand needed money.
