United States-Mexico is arguably the biggest rivalry in international soccer, an occasion that's far bigger than one game or the sport itself. For millions, it's a balancing act between two cultures, an identity exercise felt acutely by players on both sides of the rivalry. Ahead of the USMNT's trip to Estadio Azteca, ETR brings you exclusive interviews with US centerback Omar Gonzalez, former US forward Herculez Gomez and Mexico goalkeeper Moises Munoz as they detail their own experiences straddling both sides of the divide. Union forward Charlie Davies also calls in to tell the story of the famous goal he scored in 2009, and US supporter Brent Gamit explains what it's like to root for the away team at one of the most intimidating venues in the world ahead of his fourth trip to Estadio Azteca.
