What are you talking about!?
https://en.wikipedia.org/wiki/2015_Copa_Am%C3%A9ricaChile was host country and won it so they are defending champions of the Copa America title

You must be thinking of The World Cup which runs every 4 years. This one runs every few years.
Sorry, really I do not pay much attention to Copa America and did not notice this one was a special edition (I speak Spanish and know what "centenario" means, but I thought last one had been 4 years ago as usual

).
Anyway, 1 year is still a lot in soccer ...
Regarding the upcoming match, I picked over 2.5 goals (parlayed with other bets), let's see how it goes.
