I think there are 30,000 replica Chile team shirts in the Maricana. None white either, all red, despite the fact that Chile are playing in white.
I asked a Chilean friend: "So, since Argentina is the rival of both Brazil and Chile, does that mean Brazil and Chile tend to like each other?"
"Yes, oddly enough," he said.
To judge from the crowd, Chile have a lot of Brazilian fellow travelers. Costa certainly doesn't increase their appeal to the locals.
"Argentinos, maricones,
Se quitaran las Malvinas que marones."
