Realistic expectation: (BOLD are new vs last yeaer, Italics are possibilities)
GKs (3): Vicario, Perin, Pinsoglio, (hopefully a good Next Gen prospect to add?)
DEFs (8): Celik, Kalulu, Bremer, Lucumi, Gatti, Kelly, Cambiaso, Raum (I expect Cabal and Rugani to leave)
MIDs (6): Locatelli, Thuram, McKennie, Luiz, Kessie, Miretti. (I expect Koop to be loaned or sold and Miretti to stay. Arthur to go as well of course)
FWDs: (8) Conceicao, Zhegrova, Boga, Yildiz, Alajbegovic, Muani, David, Ekhator. (I don't see us doing a deal with David exiting and getting anyone else - Not sure what happens with Milik either)
Squad of 27 - which is a lot for just the Europa league. That squad is built for a 4231 because there are lot of forwards in that squad. Given what I know about Spaletti, I wouldn't be surprised that he doesn't care much for Zhegrova and David - so maybe he doesn't mind seeing both leave to bring in a big physical striker. But that looks tough to do in reality based on the current mercato.
