I've seen him a few times, the odd times I've got the chance to catch an Atalanta match I either seen him start or get some significant minutes.
The kid is good, every time I've seen him he looked bright. He's not as elegant as Pirlo, he seems a bit more taller and more aggressive but he has potential. I think it would be wise to purchase half of him, for the right price obviously, and leave him at Atalanta or loan him out somewhere.
