Here's what i think we'll see next season. It's thin because some players can slot into multiple positions. Shaw at LCB, Rashford at CF, Mount at CAM, Dalot at LB.

If it was my choice i'd go add two of these players.
Höjbjerg instead of Fofana. De Jong for Mainoo, Davies/Hernandez for Shaw & Frimpong for AWB/Dalot.
