#2 Gerardo Martino's men fall to defeat for the first time
Ever since Gerado Martino was announced as Mexico's manager in Janaury 2019, El Tri have impressed everyone with their wonderful pattern of play and won the Gold Cup despite going to the tournament without a number of key players.
Throughout his tenure, the 60-year-old has been keen on stressing that Mexico are not an elite team and that the blueprint is to get them up to the level where they would be regularly competing with the world's best national teams.
The 3-0 victory over USA last time out might have helped increase expectations, but their subsequent 4-0 demolition against Martinez' former side has shown that Mexico are still a long way off the biggest nations in the world.
When they come up against smaller teams, they regularly flex their muscles, evidenced by the fact that they have made it out of the group stage in each of the last eight editions of the World Cup they have participated in.
However, another damning indictment of their shortcomings against the top sides is highlighted by the fact that Mexico have failed to make it past the second round in each of the last seven tournaments consecutively.
Against Argentina, they bossed most of the possession, but came up short in the key areas, as their opponents obliterated them in a first half blitz.
The defeat was Mexico's first in 11 matches under Martinez and ensures that they are winless in their last 10 meetings against Argentina, with their last victory coming way back in the 2004 Copa America.
