He should be first sub for Ode but never is.
Merino is preferred to him in all midfield roles. Merino has actually been 1 of our better performers recently so I get it but I think Arteta is being very inflexible again.
He's currently fixed on Marti/Tross for LW, Gyok/Jesus for CF and Ode/Rice/Merino for the 8 roles. With Eze last choice in the 8. And not a look in at LW.
