Agree 100%.
Fagioli seems to be the real deal and could be of immediate use imo.
Miretti was a breath of fresh air and helpful to us but I do think his ceiling is below Fagioli. Fagioli has such an amazing touch, it is so enjoyable to watch. And he just went through an entire season's grind in Serie B winning young player of the competition. He fought, he clawed, and worked with his teammates to get that club promoted and went through all the emotional parts of such an endeavor.
Miretti was playing against Serie C competition and doing okay, nothing amazing, and he came up and was told to not make mistakes, play smart and play safe and he did all those things. I just don't see him as anything more than a good, cheap 5th CM and thats awesome. We need those homegrown players who can be on the squad, not cost a fortune in wages or transfer fee and contribute at decent level when called upon in Serie A or Coppa. That's it.
