I'd say last year was a write off, no system and no continuity. The whole point of the wing back is to give the people you mentioned more space by dragging defenders etc, I don't want them in the opposition box for 90 minutes but they have got to give the opposition something to think about. Look at how Liverpool exploited us in the previous game, they're full backs were brilliant and capped it off with a goal. Not saying our wingbacks are of that calibre yet bit they can do that job.The wingbacks Rose, Naughton and Walker STARVED Soldado, Lamela and Defoe last season.
You have a romantic ideal of what our wingbacks provide. Packing the midfield with Dembele, Capoue, Eriksen, Chadli and Lamela is where our attacks should be generated. It's more than enough.
And instead of Rose and co shanking chances, players who can finish should be in the final third.
