The reason the Copa America is one of the best national team tournaments in the world is that all teams compete at a very high level. There are no minnows in the Copa America despite the historical dominance by Uruguay, Brazil and Argentina.
The current tournament is no exception, as it has already had "surprises". Argentina were up 2-0 but only managed to get 2-2 against ever efficient Paraguay. In the Group where Brazil and Colombia have been seen as certain favourites, Colombia opened by a surprising 0-1 defeat to Venezuela. The Colombian superstars (James, very poor Falcao and Cuadrado, Carlos Bacca, Ospina....) were surely thinking more of their own millions than of the fact that Venezuela continues to be an extremely well-organized and committed side, deadly efficient in counter-attack and not allowing the opponents many chances.
Colombia are not better than Venezuela, that is for sure.
In the meantime Brazil had to struggle against a quite impressive Peruvian side, who had decided that the best way to play Brazil was to attack high. This gave a quite entertaining match, where Brazil's 10 Dunga clones needed the brilliance of the non-Dunga clone Neymar to make an incredible pass to set up Douglas Costa for an incredible goal.
Sad for Peru, but they can take away the fact that they are not in Chile to be easily beaten, and they surely have chances against Venezuela, and not least Colombia!
