Editing Promotion and relegation (section)

== Argentinian football and the average performance system ==
From 1957 to 1966 and from 1983 to the present, the [[Argentine Primera División|Argentine First Division]] has used a system called ''Promedios'' based on the average performance over a number of seasons. Originally the previous two seasons, and later three or four seasons, clubs avoid relegation by having a high coefficient, which is obtained by dividing the points achieved in the last three seasons by the number of matches played in the same period. Teams with the lowest points coefficient at the end of the season are relegated to the [[Primera B Nacional]].

This system has both positive and negative aspects, since all of the matches played for the championship in the last seasons are included in the coefficient for the clubs. Teams have an incentive to score points in every match of the season, meaning teams that are not challenging for the title or fighting relegation in the current season want to win even in the final matches to reduce the risk of relegation in the next season; examples are [[Club Atlético Banfield]] being champion of the Torneo Apertura in 2009 and last place in the next championship, the Torneo Clausura 2010, without being relegated until the end of the Torneo Apertura 2010 with a second-to-last place finish.

Similarly, [[Club Atlético River Plate|River Plate]] finished last in the Torneo Apertura 2008 and after two bad campaigns and a mediocre one was relegated in the Torneo Clausura 2011 despite being in fifth place and qualifying for the [[2011 Copa Sudamericana]]. This system forces the newly promoted teams to fight relegation from the very beginning of the season. It also allows teams with a low budget with previous good campaigns to compete in international competitions without having to prioritize the championship to avoid relegation; examples of this are [[Club Atlético Lanús]], winner of the [[2013 Copa Sudamericana]], or [[Talleres de Córdoba|Club Atlético Talleres]], winner of the [[1999 Copa CONMEBOL|1999 Conmebol Cup]].<ref>{{Cite news|url=http://www.goal.com/es-ar/noticias/la-historia-de-los-promedios-en-el-futbol-argentino-como-y/bjqejl02vgky1pspg5tj6ojre|title=La historia de los promedios en el fútbol argentino: cómo y cuándo se inventaron {{!}} Goal.com|access-date=2018-01-30|language=es}}</ref><ref>{{Cite web|url=https://www.infobae.com/2007/05/31/319564-la-verdadera-historia-la-creacion-los-promedios8206/|title=La verdadera historia de la creación de los promedios|website=Infobae|date=24 October 2017 |language=es-LA|access-date=2018-01-30}}</ref><ref>{{Cite web|url=http://www.elgrafico.com.ar/2012/03/02/C-4102-maldito-promedio.php|title=Maldito Promedio|website=elgrafico.com.ar|language=es|access-date=2018-01-30}}</ref><ref>{{Cite news|url=http://www.lanacion.com.ar/2099098-promedios-un-invento-argentino-que-llega-a-su-fin|title=El final de un invento argentino: los promedios dejarán de existir dentro de tres años|access-date=2018-01-30|language=es}}</ref> The [[Uruguayan Primera División|Uruguayan First Division]] adopted the same system in 2016.<ref>{{Cite news|url=https://ladiaria.com.uy/articulo/2015/10/mas-de-lo-mismo/|title=Más de lo mismo|last=ladiaria|access-date=2018-01-30|language=es-uy}}</ref> [[Paraguayan Primera División]] and [[Categoría Primera A|Colombian Categoría Primera A]] also use this same system.
