T he United States has always fascinated me. I grew up in Rosario, the Second City of Argentina, and have lived in Barcelona since the age of 13. But from what I have seen on brief visits, there is nothing like the U.S.: how Americans live, what they have. It’s a unique country. The stadiums are incredible, and I can’t imagine a better place to host a special Copa América, a 16-team mini–World Cup bringing together all the top national teams from South America and the U.S. and Mexico over 24 days in June. People tell me it will be the biggest men’s soccer event in the U.
