I think our real problem right now is our disastrous quality of our youth academy. Our academy has not produce useful good talent since Marchisio, and that is 15 years ago. There are some real talents like Giovinco or Kean, but they have s**t mentality and waste their talent. If you see big clubs in Europe, all of them has produced quite a few useful players for first team squad, unlike us. Even worse, I didn't see any of our ex-youth player become good in Serie A for a long time.
In the era of high transfer fee right now, having some solid player come from youth academy will help club better focus the resource to better/high profile player in important position. We don't need them to be world class like Xavi, just solid enough to be reasonable backup. With our disastrous youth academy, we are in real disadvantage as we need to buy everyone from starters to backup, and with our not-so-great income, there will be hard for us to assemble a great squad
