This practice, long established in the major North American sports, is a recent development in football elsewhere, since squad numbers for specific players were not widely used until the 1990s. Before then, it was typical for players in the starting lineup to be issued numbers 1 to 11 by formation/position on a match-by-match basis, and substitutes to be numbered from 12 upwards, meaning a player might wear different numbers during the season if they were to play in different positions for tactical reasons, or simply not be a regular in the starting lineup.
In contrast, in the American league NASL, players have always worn permanent numbers since its inception in 1967.[2] Moreover, Pelé's #10 was retired by the New York Cosmos during the farewell of the Brazilian star on 1 October 1977,[3] probably becoming the first number ever retired in association football.[4]
Mexico was a pioneer country in the use of permanent numbers in football; these were adopted in the Primera División in the 1980s.[5]
The Argentina, Ecuador and Cameroon national teams have been prevented from retiring the numbers of Diego Maradona (10), Christian Benítez (11)[7] and Marc-Vivien Foé (17), respectively, by FIFA rules dealing with squad numbers for Finals tournaments; in other competitions, qualifiers or friendlies, national associations may assign numbers according to criteria of their choosing. Similarly, several clubs have been required to reissue retired numbers for continental club competitions due to squad numbering rules of continental confederations. For example, CAF[8] and CONMEBOL have such rules in their club competitions,[9] but CONCACAF does not.
Some South American teams (such as Universitario de Deportes and Flamengo, and even Mexican teams invited for the occasions) occasionally had to re-issue their retired numbers for special cases due to CONMEBOL rules, which stated that shirts had to be numbered 1–25/30 in continental club competitions (such as Copa Libertadores and Copa Sudamericana, among others), although nowadays clubs are not forced to number their players consecutively.
