In European football, the UEFA coefficients are statistics used for ranking and seeding teams in club and international competitions. Introduced in 1979, the coefficients are calculated by UEFA, who administer football within Europe. For men's competitions (discussed in this article), three different sets of coefficients are calculated: *National team coefficient: used to rank national teams, for seeding in the UEFA Euro qualifying and finals tournaments *Country coefficient: used to rank the collective performance of the clubs of each member association, for assigning the number of places, and at what stage clubs enter the UEFA Champions League and the UEFA Europa League *Club coefficient: used to rank individual clubs, for seeding in the UEFA Champions League and UEFA Europa League While not discussed in this article, coefficients are calculated in a similar fashion for women's competitions such as the UEFA Women's Euro〔(【引用サイトリンク】title=UEFA Women's National Team Coefficient Ranking )〕 and the UEFA Women's Champions League,〔(【引用サイトリンク】title=UEFA Women's Champions League Association Coefficient Ranking )〕〔(【引用サイトリンク】title=UEFA Women's Champions League 2012/13 Entry List )〕 as well as for youth tournaments such as the UEFA Euro U-21 tournament.〔(【引用サイトリンク】title=Spain and Israel top seeds for Under-21 draw )〕 ==National team coefficient== The UEFA national team coefficient is derived from the results of each European national football team, and only calculated by UEFA every second year in November; defined as being the point of time when all UEFA nations have completed the qualification stage of the upcoming World Cup or European Championship tournament. The purpose of calculating the coefficients is to compile an official UEFA rank, to be used as seeding criteria for the European nations, when drawing up qualification groups and the final tournament groups of the European Championship. Previously, up until 2006, the UEFA national team coefficient was also used for the seeded draw of World Cup qualification groups in Europe, while the draw for final tournament groups of the World Cup was always seeded on the basis of the official FIFA World Rankings. The reason why UEFA stopped using UEFA national team coefficients for the seeding of World Cup qualification groups was a request from FIFA to only use the official FIFA ranking for all seeded draws related to the World Cup tournament. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「UEFA coefficient」の詳細全文を読む スポンサード リンク
