Argentina reported on its Web site that it will play Mexico in San Diego on June 4 and against the United States on June 8 at Giants Stadium.
From the report on the Argentine FA's Web site:
The Argentine national team will take a mini-tour through North America in June. Alfio Basile's squad will face Mexico in San Diego on the 4th of that month and will play four days later against the United States in New York. In both cases, neither the time nor the stadium has been set.
Our national representatives will use the matches as preparation for qualifiers that will be played on the 14th against Ecuador in Buenos Aires and on the 18th in Brazil against the hosts. Both games will serve as qualifiers for the 2010 World Cup in South Africa.
