Well Jones never stops covering for whoever is at right back. 5 midfielders should be able to offer more protection especially when one of them isn't expected to offer anything going forwards.If your wide midfield players simply don’t track back and think about defending now and again the full backs, as they are time and time again, are being left completely exposed. You could stick Trippier, Kyle Walker, TAA - whoever you like at full back for the Boro - they can’t do it on their own and even they would struggle playing behind these two.
