Brazil and Mexico, two teams who won their opening games in Group A, will face off against one another on Tuesday afternoon, with only one team able to emerge with their 100 percent record intact.

Today's big game will take place at the Estadio Castelao in Fortaleza and will kick off at 3 p.m. EST. The game is scheduled to be broadcast on ESPN, but can also be watched online through live stream - free for subscribers - via the link provided below.

Brazil are massive favorites to win Group A, but Mexico are a sort of bogey team for the host nation. In fact since the turn of the century, no other team in the world has defeated Brazil more times than Mexico.

To show Mexico's achievement, their record over the last 13 games between the two teams shows that Mexico have won an impressive 7 of those games, drawing 2, and losing just 4 times.

Not many teams can boast such a fantastic record against the most successful World Cup nation, and that will mean that Brazil will be ultra careful today and not taking anything for granted.

However, Brazil have perfect record over recent games coming into this match up. They have won 10 straight games, scoring an impressive 33 goals and conceding just 3.

Even worse news for Mexico, when it comes to matches in Brazil, the host nation are currently 38 games undefeated on home soil; their last defeat while playing in Brazil goes back more than a decade when they lost against Paraguay in 2002!

The Brazilians currently also have wonderkid Neymar on their side. He has scored an amazing 33 goals in just 50 appearances for his country, and 24 goals in his last 29 international appearances. If Mexico are to pull off a shock today they will have to keep Neymar quiet.
