I guess I have a harder time seeing Mexico as impressive when I look at their performances against USA. When’s the last time they beat us in a game NOT played in Mexico City? It’s been a while.
USA has problems in Mexico as well. August 2012, we won a friendly. I don't know if we have defeated them in a competitive game there yet, I thought we did. Mexico was going to World Cups many times before we finally went in 1990 after going last in 1934.
Looks like Mexico did defeat the USA June 25 at the Gold Cup in the USA, 4-2.
