Argentina, with the sportinguista Marcos Acuña starting, beat Mexico 2-0 at home in a private game in Cordoba, where goalkeeper Jesus Corona did not leave the Mexican bench.
In the absence of stars such as Messi, Agüero and Di María and the international players of River Plate and Boca Juniors, concentrated in the 100% Argentinian final of the Libertadores Cup, Dybala took the lead, and it was his feet that left the free for central Ramiro Funes Mori to make a first goal, with 44 minutes.
Before the goal, Mexican goalkeeper Guillermo Ochoa had already caught a header from Lautaro Martínez and a free-kick from Paulo Dybala, but the first signs of danger were given by Mexico when Raúl Jiménez (formerly Benfica) threw the bar, in the 04th minute, and Marco Fabian forced Agustín Marchesin into a close save for the corner, at 06.
In the second half, there were not so many dangerous moves, and 2-0 came in the 83rd minute, following a well-crafted Argentina move from the right, when defender Isaac Brizuel finished off an own goal in an attempt to keep the low cross from Renzo Saravia to Mauro Icardi.
Argentina and Mexico meet again on Tuesday for a new individual in Mendoza.
