FIFA to rank the progression and ability of the national football teams of its member nations, and claims that they create "a reliable measure for comparing national A-teams". They are used as part of the calculation, or the entire grounds to seed competitions. In the 2010 FIFA World Cup qualification tournament, the rankings were used to seed the groups in the competitions involving CONCACAF members (using the May rankings), CAF (with the July set of data), and UEFA, using the specially postponed November 2007 ranking positions. The October 2009 ranking was used to determine the seeds for the 2010 FIFA World Cup final draw. The March 2011 ranking was used to seed the draw for the 2012 CAF Men's Pre-Olympic Tournament second qualifying round. The rankings are also used to determine the winners of the two annual awards national teams receive on the basis of their performance in the rankings. The (English) Football Association uses the average of the last 24 months of rankings as one of the criteria for player work permits. Special releases To determine the seeding of teams in certain instances like FIFA World Cup qualification, FIFA occasionally releases a list of special rankings for a particular confederation to determine the seeding of the teams. For instance, the seeding for the third round draw for AFC qualifiers was based on a special release of the FIFA World Rankings for Asian teams on 18 June 2021. Criticism of pre-2018 methods Since their introduction in 1992, the FIFA World Rankings have been the subject of much debate, particularly regarding the calculation procedure and the resulting disparity between generally perceived quality and world ranking of some teams. The perceived flaws in the FIFA system have led to the creation of a number of alternative rankings from football statisticians. The initial system was very simple, with no weighting for the quality of opponent or importance of a match. This saw Norway reach second in October 1993 and July–August 1995, a ranking that was criticised at the time. The rankings were adapted in 1999 to include weightings based on the importance of the match and the strength of the opponent. A win over a weak opponent resulted in fewer points being awarded than a win over a much stronger one. Further adaptations in 2006 were made to reduce the number of years' results considered from 8 to 4, with greater reliance on
