The move to a fixed number being assigned to each player in a squad was initiated for the 1954 World Cup where each man in a country's 22-man squad wore a specific number for the duration of the tournament. As a result, the numbers 12 to 22 were assigned to different squad players, with no resemblance to their on-field positions. This meant that a team could start a match not necessarily fielding players wearing numbers one to eleven.
