I don't think Pep will do this, but I really want him to play Walker RB and Stones CB, and just have Stones step into midfield from CB rather than RB, and allow Walker to cover the wide areas and be the RCB when they form that back 3.
So instead of Ake-Dias-Akanji behind Rodri-Stones, it's Aké-Dias-Walker behind Rodri-Stones.
