Ahead of its Copa America semifinal against Peru, Uruguay moved training base to the home of Argentine clausura champions Velez Sarsfield -- a complex that apparently has a very strict dress code. The only football shirts that visitors are allowed to wear at the facility are those of Velez or Argentina's national team. All others (especially Brazil's) are prohibited.
Exceptions are made for teams participating in competitions or anyone on official business. But if you show up wearing, say, a Kaka shirt just for the fun of it, they will shoot you on sight.
OK, they probably won't shoot you. But prolonged torture seems like a strong possibility.
