Ake being left footed and homegrown should keep him around.
Akanji can play basically everywhere in the backline (not better than any of our players though) so his adaptability should keep him around.
Stones has to go, and while I think he is the best defender we have, can't be relied on.
Khusanov on the other hand, is young enough to be molded into whatever Pep envisions.
I currently envision him to be adaptable similar to Jules Kounde.
RCB in a back 4 if both fullbacks bomb wide.
RB in a back 4 as well (like Kounde is currently doing) wherein only the LB bombs wide, but the RB has 3 phases of positioning:
1) RCB in the 1st phase of possession to make sure the team is settled.
2) RCM in the 2nd phase when the team is pinning the opposition back, he doesn't need to be RCB, he needs to be a bit higher to counter press immediately.
3) RWB in moments in a potential 3rd phase wherein the RW drifts in and he can give him an option as a wide fullback with his pace (we see Akanji try to do this but he is so hesitant as its not natural to him like it is Kounde).
