No point in looking for a GK. Szczesny has proved himself completely, I don't believe anyone could come in and do better right now. And we got Perin on the bench, no reason to mess anything up on that position.
We need a CM, some full-back cover if Sciglio and Spina are permanently fucked, a younger Chiellini and then a proper striker, as Mandzukic is not getting better and we need an alternative soon.
Piatek, De Lict seems interesting and affordable.
