Even more demanding is the role of wing-back, where the wide player is expected to provide both defence and attack.[54] As the role of winger can be classed as a forward or a midfielder, this role instead blurs the divide between defender and midfielder. Italian manager Antonio Conte has been known to use wide midfielders or wingers who act as wing-backs in his trademark 3–5–2 and 3–4–3 formations, for example; these players are expected both to push up and provide width in attack as well as track back and assist their team defensively.[55]
