The FIFA Men's World Ranking is a ranking system for men's national teams in association football, led by Brazil . The teams of the men's member nations of FIFA, football's world governing body, are ranked based on their game results with the most successful teams being ranked highest. The rankings were introduced in December 1992, and eight teams (Argentina, Belgium, Brazil, France, Germany, Italy, the Netherlands and Spain) have held the top position, of which Brazil have spent the longest ranked first. A points system is used, with points being awarded based on the results of all FIFA-recognised full international matches. The ranking system has been revamped on several occasions, generally responding to criticism that the preceding calculation method did not effectively reflect the relative strengths of the national teams. Since 16 August 2018, the ranking system has adopted the Elo rating system used in chess and Go. The ranking is sponsored by Coca-Cola; as such, the FIFA/Coca-Cola World Ranking name is also used. Coca-Cola also sponsors the women's counterpart. History In December 1992, FIFA first published a listing in rank order of its men's member associations to provide a basis for comparison of the relative strengths of these teams. From the following August, this list was more frequently updated, to be published most months. Significant changes were implemented in January 1999 and again in July 2006, as a reaction to criticisms of the system. Historical records of the rankings, such as listed at FIFA.com, reflect the method of calculation in use at the time, as the current method has not been applied retrospectively to rankings before July 2006. Membership of FIFA has expanded from 167 to 211 since the rankings began; 211 members are currently included in the rankings. The Cook Islands were temporarily removed from the ranking in the period from September 2019 until February 2022, after not having played any matches between 4 September 2015 until 17 March 2022. 1992–1998 calculation method The ranking formula used from December 1992 until December 1998, was devised by two Swiss lecturers from University of Zurich (Markus Lamprecht and Dr. Hanspeter Stam). The first formula was the most simple one, compared to later revisions, but it still required complex calculation. The main concept was to award points for matches played between all FIFA-affiliated national A teams, based on their results over the past eight years in FIFA-recognised matches (friendly matches, qualifying
