Here comes the big one.

Before the Copa America started, people knew they had to pencil in the June 17 date between Colombia and Brazil. Two juggernauts who had played to an edgy match in last year's World Cup were bound to bring about some attacking flair and drama.

What drama it has turned out to be.

Brazil enters the game fresh off a nervy 2-1 win over Peru that relied on the team's complete resources and some magic from Neymar.

Colombia enters the game desperate for three points and knowing full well that a loss here coupled with a Venezuela win essentially puts its tournament aspirations on life support.

Brazil will undeniably be favored to win thanks to Neymar, the gift that keeps on giving. While Lionel Messi continues to baffle as Argentina's leader, Neymar simply produces wins. He scored and assisted in the Peru game and could have had more if he would not have fired one shot wide or wrung the ball off the bar on another.

The defense was suspect against Peru, and this will certainly give Dunga some nightmares against a potentially dangerous Colombian attack.

The key word is "potentially" because Colombia's potential was not visible in its 1-0 loss against Venezuela. In fact, one had to wonder if it was possible that the Colombia side that slumped so poorly against Venezuela was the same exciting group of attacking swashbucklers from the 2014 World Cup. Colombia simply had no answer for Venezuela's tight pressure in the middle of the field and often resorted to sloppy long range efforts that came of no avail.

James Rodriguez was a shadow of the superstar that dominated Brazil last summer or even the key star on Real Madrid's offense. He looked frustrated, constantly being harassed by Venezuelan defenders in a manner similar to Brazil's defending in the World Cup last summer.

He will likely have to deal with more of the same in this game. If he makes adjustments, then Colombia might be able to unpack Brazil with greater facility.

That of course could happen naturally given the two sides in contention.

Venezuela lacked much talent throughout, so it relied on pressing and compact defending to frustrate Colombia and find openings. Colombia was thus given possession and forced into playing a slower possession game that does not suit the Cafeteros.

Brazil will likely attack, thus allowing Colombia to play its quick free flowing attacking style. That alone could help Colombia find its mojo.

One other thing that could help Los Cafeteros is the benching of Radamel Falcao in favor of Jackson Martinez or Teofilo Gutierrez. The former put up 21 goals in Portugal this season while the latter was a hit in Argentina.

Both provide Colombia with more pace than Falcao, who looked slow and lost in the 1-0 loss. That alone should open up space for Carlos Bacca, who was rendered futile in the Venezuela game.

Brazil wins if... Neymar continues to conjure his magic. This team looked rather listless without Neymar's attacking flair or WIllian's involvement.

Colombia wins if... it finds a way to be more physical and play its run and gun style against a brittle Brazil defense.

Prediction:   A 1-1 draw.
