Your missing the point though. We have supposedly a future LB but unless he shows something special in training, he cant be backup.
So what do you do? Spend a chunk on a different player, like I said above, Jamaal Lewis for instance. Or do you loan a player? That still involves a fee and wages. Or do you get an experienced Championship player in who is similar to Baines and Digne in that hes good going forward (has more pace though), he knows the club, is only backup and if we did want to sell after a year would make a £5-6mill profit.
