InterLiga

The InterLiga was a football competition from 2004 to 2010 between Mexican clubs to determine qualifying spots for that country in South America's premier club competition, the Copa Libertadores.

Prior to the 2004 Copa Libertadores, Mexican clubs competed in two levels of competition—first against one another, and then against clubs from Venezuela—for spots in the main competition. In 2004, Mexico and Venezuela were granted automatic entries to the Copa Libertadores for the first time. The Mexican Football Federation decided to create a qualifying league for its two automatic spots, and the first InterLiga was held that January, during the off-season of the Mexican Primera División.
