Alexandr Golovin - talented all-rounder and one of Russians who can do playmaker role (with Dzagoev, Miranchuk brothers and Erokhin), linked with Arsenal. Also good in defensive part of the game.
David Kownacki - hope he gets playtime when Lewy and Milik are rested, good striker in Sampdoria who has great goal ratio knowing he isn't starter over there.
Amine Harit - one of best dribblers in Bundesliga, and one of most fouled players. He primarly plays as right side winger but can also fit centrally. I hope he gets a lot of playtime.
Manuel Akanji - been real suprise for Dortmund, played as CB and fullback, and apparently very good with Swiss NT. I see him as one of best CBs in few years (atleast in Bundesliga).
Pione Sisto - had impressive season in La Liga with Celta, one of rare pure Danish wingers (who is actually good), he will probably start.
I'd agree with your picks too, but Jesus is well-known already, Bentancur maybe too (Allegri tested him in bigger matches).
