Danilo has been playing CM for Santos more recently, but I've seen him more at the RB spot where I thought he was good. He seems to be a very multi-faceted player who can really do it all, plus is somewhat quick. I don't know if he can play on the left side, however, but it wouldn't surprise me.
I'm all for signing Danilo and young South American talents like him. But I just wish we would go after the more technical and exciting prospects like a few of his teammates.
It's hard to know what sort of player Marotta and Conte see him as, apart from a good one to loan.
