Well, I was born in Mexico, so I root for Mexico.
I live in the US, so i root for the US whenever they don't play Mexico.
Pick a team. Cheering for both teams is like cheering for the Cardinals & Cowboys. I hate people who CHOOSE to live in this country yet don't support our team first and foremost.
Mexico won the Gold Cup against a squad full of guys who won't make the WC squad, only 2 players for the US even made the squad against Mexico in February.
The US may not win in that dump in a pit of a city in Mexico but Mexico won't win 5-0 either. Mexico truly has homefield advantage there--most polluted city in North America, high altitude and 100K+ fans.
Anyways back to the game (I was in Minnesota without internet this past week so I couldn't comment earlier)...if Heaps, Arnaud or Pause see another game in a National team kit then Bradley is a worse coach than I imagined.
Dos Santos is awesome, if they named a player of the tournament it'd have to be him(he did dive on that PK call though but otherwise was awesome).
