Coman as a super sub could play LWB, RWB, AML, AMR, or even bring forth a formation change, all depending on opponent and situation. But they still need 2 more wingbacks for rotation and i heard Robbery stays another season, so 3421 might not be it

Kimmich should be fine as a starter, gonna need a backup tho. Alaba might be a LCB again like with Pep, but even if hes a LWB they still need another player to rotate with him (Asamoah is available on a free

)
