Bear with me here. Whenever Jonny Howson has covered at centre back he has looked excellent. Composed, cultured, great anticipation. He may be getting a bit long in the tooth to play defensive midfield for us at the level we need, mobility wise. I reckon he'd be fit and mobile enough to play CB until he is 40 though. So, if he was up for it, rather than buying Edmundson as back-up CB, would it be better to see if he wanted to extend his career with a view to being mainly CB cover, but with the option of being emergency cover in midfield too?
