We are not going to see much of Nwaneri this season I don't think. Ethan for Ode, in my view, is still a huge ask. It's "easier" to accommodate Ethan for Saka. When you lose the ball or don't do the right things on the wing and close to the opponents final third, it's less costly than if you get caught playing in the middle. And once Madueke is back, we are unlikely to have Ethan start or sub in in place of Saka, as what does he bring to the table that's really different or special on the wing?
Eze will always be the primary replacement for Odegaard through the middle.
