Caldara is coming in, no central defender needed. Spinazzola coming in fills both fullback positions, probably replaces Lichtsteiner. Need to retain Alex Sandro but he might be the big loss. Without that sale the defence looks stacked, especially if Asamoah renews.
Strikers, retain Pjaca and the rest is absolutely fine.
It's midfield. Khedira. Continually injured Marchisio. Sturaro. Only Pjanic and Matuidi offer some guarantees, and Bentancur stays as the quality prospect. That is 2 players needed in CM, the only place where cash needs to be spent. But then there is always the chance of a random huge sale...who knows.
