I think id like to see him play RW more, if only to balance the team better.
Lets Grealish play LW more, gets Foden in the middle and while Foden is doing well on RW, we need his creativity and goals in the middle more than 1v1 dribbling on the wing which Doku has.
Doku isnt much of a goal scorer right now, he is a wing creator like Grealish (who cant score but can create).
This means we need our middle players to be goals, and currently thats a big strength of Foden.
Foden paired with Bernie would be great, Alvarez false 9 if Haaland is out.
