To be fair to Lalas, almost all of the Mexican fans at the game live in the United States and some are Americans. It's almost impossible to overstate the insecurity of the average Mexican soccer fan regarding this second stage evolution of U.S. soccer. They did not anticipate the avalanche of young U.S. players moving to the Big 5 leagues and are beginning to realize that the depth of legitimate international American talent is real and only going to increase while the Mexicans will remain the same Mexico they have been since the 80s.
Mexican fans are generally tolerable when they are winning but they are cornered rats when losing, particularly when losing to their hated American rivals. Anyone who has watched the U.S. win a game against Mexico outside of Columbus and SLC has experienced the sad descent of the Mexican fans to paranoia, self-loathing and violence when the U.S. closes in on victory. They are losing in real time the one thing they care about the most and the one thing they have had over the gringos. The aggy analogies are disturbingly apt. The mindset of aggy toward Texas is almost indistinguishable from the mindset of the Mexican team and fanbase towards the USMNT. The violent and disruptive behavior of the Mexican players and fanbase will only continue to deteriorate in the coming years as the Americans win game after game against them. The gamesmanship (aka cheating) of the Mexican team is going to reach unprecedented and pathetic levels over the next decade as their futile resistance to American domination of the rivalry collapses.
Mexico may not beat the US for 10 years outside of Azteca if the US fed hires a real coach. It's all over for the Mexicans and they know it.
