Mexico and Argentina have faced each other on 24 occassions with Argentina having won 9 times and Mexico 4, with 11 draws in all.
The last time Mexico’s Tri defeated tonight’s opponents was in the 2004 Copa America in the group stages thanks to a goal by Ramón Morales.
But since then the two sides have played each other three times, drawing a friendly in Los Angeles while Argentina knocked Mexico out of the 2005 Confederations Cup on penalties and then beat them in extra-time in last year’s World Cup the occasion of Maxi Rodriguez’s wonder goal.
Tonight is Mexico’s fifth Copa semi-final since they were first invited to participate in 1993. They’ve twice reached the final, losing to Argentina in 1993 in Ecuador and then to hosts Colombia in 2001. Argentina have won the Copa 14 times.
