I really think he's going to play in midfield a lot more because we need both him and Walker in the side.
Pep tried the Walker CB idea to get them in the same team, not sure that worked, so the obvious next step is Rico playing next to Rodri. Pep's selection tonight showed that Bernardo and KDB are not undroppable.
I think it would really suit him too, you can see he wants to get forward more but is holding back so he can do his RB responsibilities, and he's already developed a great relationship with Rodri, combining quick 1-2s and movement to beat the press and getting each other out of trouble when they're under pressure.
