No to Ibarbo. He is not much better than Biabiany, except being little stonger. His first touch is shit, his finishing is shit, even tho his longs shots are decent. I haven't seen him crossing. He is strong tho and very fast, but that's pretty much it.
I'd love Sau and Nainggolan tho. Great players. Astori is a bit overrated by the italian media and that has hit the fans head. He is good, but no better than Rano or Campagnaro atm, and cant play as LCB. So no thanks.
