Qualification
The teams involved were selected based on qualification rules set by their respective leagues.
On November 21, 2008, MLS announced that for the 2009 tournament, the top four teams in the 2008 MLS regular season standings not competing in the CONCACAF Champions League in 2009-10 would qualify for SuperLiga 2009. That ruling means that the top two teams from the 2008 MLS season, the Columbus Crew and the Houston Dynamo, who had already qualified for the CONCACAF Champions League 2009–10, were not eligible to participate in the Superliga 2009.
On May 14, 2009, FMF announced that for the 2009 tournament the top four eligible teams from the Clausura 2008 and Apertura 2008 overall season standings not competing in the CONCACAF Champions League would qualify for SuperLiga 2009. That ruling meant that the Apertura-08 Champion Toluca and the runner-up Cruz Azul (2008 3rd and 4th overall respectively), who had already qualified for the CONCACAF Champions League 2009–10, were not eligible to participate in the tournament. Guadalajara (2nd overall) and UNAM (6th overall) declined to participate.
