Common modern formations that include left and right midfielders are the 4−4−2, the 4−4−1−1, the 4–2–3–1 and the 4−5−1 formations.[14] Jonathan Wilson describes the development of the 4−4−2 formation: "…the winger became a wide midfielder, a shuttler, somebody who might be expected to cross a ball but was also meant to put in a defensive shift."[15] Two notable examples of wide midfielders are David Beckham and Ryan Giggs.[16]
