As one of the six FIFA confederations, CONCACAF is in charge of World Cup qualification for its member teams. It also runs its own competitions, including the Gold Cup for international sides and the CONCACAF Champions League for clubs.
At the international level, the confederation has been controlled by the United States and Mexico who, between the two of them, have earned more than half of the confederation's World Cup appearances. Mexico has advanced the furthest, making it to the World Cup quarterfinals in 1970 and 1986 (both times as the host country). El Tri also dominates at the club level, with the three highest-ranked clubs at present (Cruz Azul, Pachuca, and Deportivo Toluca) all coming from Mexico's Primera División.
Curiously, CONCACAF also includes three South American teams--Guyana, French Guiana, and Suriname.
