I'd also be curious if he'd look at a back 3 of Tarkowski, O'Brien and Branthwaite, then use wingbacks, which probably suits the squad a lot more. When fully fit we're fine, it's the depth and injuries that really could mess with that, as we're seeing now.To be honest I suspect the full back situation is one Moyes is reasonably happy with if everyone's fit. We have 2 decent (albeit not great) options and a 3rd less decent one for both positions:
LB: Mykolenko / Branthwaite / Aznou
RB: O'Brien / Garner / Coleman
