The G-14 is an organization of European football clubs. It was founded in September 2000 by 14 leading clubs to provide a unified voice in negotiations with UEFA and FIFA. New members may join by invitation only. In August 2002, four more clubs joined, taking the membership to 18, although the organization has retained its original name.
Essentially a pressure group, they have often been linked to various initiatives to create what the media have called a European Super League, although this is often denied. These reports were particularly common during 2003 when UEFA took the decision to drop the second group phase from the Champions League without the consultation of the participating clubs. G-14 took this as justification that they are needed within European Football to create what they call a ‘voice for the clubs’. The president of the group is Olympique Lyonnais chairman Jean-Michel Aulas, who replaced David Dein who stepped down after 6 months of a two year presidency after leaving Arsenal.
The G-14 clubs are spread across seven different countries, and have won around 250 national league titles between them. Three come from each of the top divisions of England, France, Germany, Italy, and Spain; two from the Netherlands; and one from Portugal. G-14 members have won the European Cup/Champions League 41 times out of 51 seasons.
The 2004 Champions League final was the first in that competition since 1992 in which one of the finalists was not a current G-14 member; the 2004 final featured member Porto and non-member AS Monaco. There have been only three Champions League or European Cup finals where both teams were non-members of the present G-14.
In the other existing major UEFA club competition, the UEFA Cup, fourteen finals have featured two non-members, compared to only three that have featured two G-14 clubs. 2005 was the first final since 1989 to be contested between two non-members - CSKA Moscow and Sporting Lisbon. In 2006, the UEFA Cup was contested again between two non-members Sevilla and Middlesbrough, as well as in 2007 when Sevilla played Espanyol.
