Turn that 3-4-2-1 to a 4-3-3 with Loftus-Cheek in midfield, Chukwueze as RW, Leao as LW, Estupinan as LB, and bring in a right back for Terracciano, then everyone is in a more comfortable position. 11 out of 11 players in positions they are comfortable with only one player change, and I reckon Terracciano could easily do a job at RB too.
AC Milan appointing him reinforces my belief that I'd do a much better job than a lot of the people top professional clubs have making football decisions for them.
