I think the interesting thing is which one does EtH go for?
Either a young-ish RCB to give rest to and learn from Varane or a left-footed LCB to cover for Martínez. I know we have Shaw but if he replaces Licha when needed, our rotation LBs are not that good.
I would certinaly go for left footed CB precisely for the reason you mentioned. Drop off at LB too big whenShaw is not there. I reckon Lindelof is a good deputy for Varane.
