I think we should go all in for SMS! He's the only player who can really improve our team! If we get him, I don't mind us getting Darmian.
We sell Khedira, get SMS, and Emre Can, keep Marchisio, Matuidi and Bentacur on Bench and our midfield is pretty good!
If we can cash in for Benatia that would be good! Rugani, Caldara, Chiellini and Hoewedes are good enough!
