Modeled after the widely popular UEFA Champions League, the SuperLiga will include a group phase and knockout phase, with all games being held in US venues from July 24 to August 29.

"We are proud to announce the creation of SuperLiga, which will quickly become one of the most prestigious international club soccer tournaments held in the United States," MLS commissioner Don Garber said Saturday.

"This tournament presents the most authentic competition between rival soccer nations and will bring out the passion and pride of fans in our hemisphere."

Group A will consist of MLS clubs FC Dallas and the Los Angeles Galaxy - the new home of English superstar David Beckham - and Mexican teams CD Guadalajara and CF Pachuca.

Group B will contain DC United and the Houston Dynamo of MLS and Club America and Monarcas Morelia of the Mexican league.

"Given the great soccer rivalry between the two countries, we strongly believe SuperLiga will be a great international soccer tournament," Mexican commissioner Decio de Maria said.

"Featuring the top teams in both leagues, SuperLiga will become an instant favorite among the millions of soccer fans in Mexico and US."
