Wingers such as Stanley Matthews or Jimmy Johnstone used to be classified as forwards in traditional W-shaped formations, and were formally known as "Outside Right" or "Outside Left," but as tactics evolved through the last 40 years, wingers have dropped to deeper field positions and are now usually classified as part of the midfield, usually in 4–4–2 or 4–5–1 formations (but while the team is on the attack, they tend to resemble 4–2–4/2–4–4 and 4–3–3 formations respectively).
