Another bullet dodged.
Eh, I think he could have been useful to platoon with Foyth for the 3rd CB position in a back 3.
Assuming Toby leaves, we still need to sign somebody in CB, unless we are planning on more heavily using Dier as a CB. Even then, we'd only have 4 CBs on our depth chart, one of which is also on our CM depth chart, meaning need to sign two CMs if we are also selling Dembele.
If we are planning on promoting CCV, that could work also, although it'd be pretty underwhelming after all this talk of a big transfer window.
