High Quality Content by WIKIPEDIA articles! In the sport of association football, each of the eleven players on a team is assigned to a particular position on the field of play. A team is made up of one goalkeeper and ten outfield players who fill various defensive, midfield and attacking positions depending on the formation deployed. These positions describe both the player's main role and their area of operation on the pitch. As the game has evolved, tactics and team formations have changed, and the names of the positions and the duties involved have evolved as well. The fluid nature of the modern game means that positions in football are not as formally defined as in sports such as rugby or American football. Even so, most players will play in a limited range of positions throughout their career, as each position requires a particular set of skills. Footballers who are able to play comfortably in numerous positions are referred to as "utility players". However, in Total Football tactics, the players are only loosely defined into a position. This tactic required players who were extremely versatile, such as Johan Cruijff, who could play every position on the pitch apart from goalkeeper.
