Not invited. Mexico, however, will send its Olympic 2012 team to compete, not the team from the Gold Cup. Yeah, you guys only showed up one time to Copa América, but I'd rather NOT talk about it, sirs.
Kind of off-topic, but I just saw an interview with Steven Cherundolo on German TV for the first time, and I hate to say it, but I think his German is better than my English...at least more accent-free. I was surprised to see that because I have met many US soldiers based in Germany, who, after >10 years in Germany could not speak a lick of German.
