I have to be honest with you. I was thinking about this same exact scenario when I read the article in FI, as far as what would be fair return for Pogba. A bit of cash, though, in my opinion, whould be 20 million. I know it's a lot, but that comes out to 70 million, which is what Pogba's rumored value is anyway.
With that money, they can get themselves a decent winger up front with De maria, have decent enough depth at the midfiled with a 4 man rotation of Pirlo-Vidal-Asamoah-Marchisio.
They shore up their left back problem with Coentrao, move Licht down to RB, and now there is tremendous depth in the defense with Licht, Bonucci, Chiellini, Caceres, Coentrao, Barzagli, Ogbonna.
