Me too - except when Mexico is the underdog. My desire to see them lose is purely sporting, but I don’t buy into this movement for USA fans to support them. They are our biggest rivals.
Mexico’s counterattacking plan bore fruit against a German side that were partly flat, partly unlucky. I disagree with those pundits who claimed Mexico ‘dominated’ parts of the match (I heard some of that on FS1 in the post match analysis). They defended pretty stoutly, created a few good counterattacks and scored on one, and had a slice of luck. Germany tried to force their way through a crowded middle zone and were too eager to shoot when a more patient approach using more width, and one that utilized their height advantage with crosses, would have served them better.
It’s a symbolically huge win for Mexico, but from a German perspective it’s the least important match they will play in this tournament - and despite not playing all that well they should have at least drawn it. As for Mexico, South Korea and Sweden will not press them like the Germans did, so I expect they will find it harder to get behind those defenses with longballs and threaded passes.
