IMO signing Odegaard changes the need re RB, as we have the attack front5 sorted - KT, ESR, CF, MO & Saka with Pepe, Martinelli on rotation. I suspect the only way we look to sign an attacking RB is if we change shape, otherwise I mainly see the RB role as being more akin to either an inverted FB looking to linked up in a midfield3, or as staying with the CBs to form a back3 when KT goes forward.
As much as I want a CF who better fits the role Arteta wants I don't see it happening this summer, and I think PEA will be our starting CF playing in an advanced/pressing forward role, as PEA isn't suited to play a linking/false9 role and MO is more an Ozil playmaker type than being a Fabregas/Buendia type looking to make runs beyond the CF.
My #1 priority is CM to partner Partey & my 1st choice would be Sabitzer unless he has signed a new deal.
