Group A action continues on Tuesday with another great match: Brazil vs. Mexico. Both clubs won their openers easily, although Brazil was the beneficiary of a very controversial call which helped them tremendously. Mexico's opener was also not without drama; the club had two goals nullified due to some questionable offside calls.

According to Bleacher Report, these two clubs are expected to advance from Group A, so the winner of Tuesday's match could very well advance in the top spot, which raises the stakes for what will only be either clubs' second match.

Evenly Matched - While Brazil is still the overall tournament favorite, Mexico has had success against their squad in recent years, most notably in 2012 when Mexico defeated the Brazilians in the Olympic final match. Brazil found a way to get even the last time these clubs faced each other, with a dominant 2-0 performance at last year's Confederations Cup.

Injury Report - According to MLS Soccer, Brazilian striker, Hulk, has an apparent left leg muscle injury. Hulk came up lame during Sunday's team workout, and his status is uncertain for Tuesday's game. Hulk insisted he will be ready to go at kickoff, but if he is not 100 percent, Brazilian coach Luis Felipe Scolari may have a difficult decision to make regarding his lineup.

Then there is the issue of Neymar's ankle. The Brazillian star turned his ankle last week during training, though it didn't appear to bother him as he scored two goals in the opener against Croatia. But should Neymar aggravate the injury further, it could prove to be disastrous for the host country's title hopes.

Players to Watch

Giovani dos Santos, forward, Mexico - If not for some very controversial calls in Mexico's opener, dos Santos would have two more goals to his tournament tally. Although he has the talent to help Mexico make a deep run in this year's tournament, dos Santos will have to overcome what has been billed as his biggest weakness: inconsistency. Can dos Santos have two great games in a row when his team needs it most?

Paulinho, midfielder, Brazil - Consistency will also be key for Brazil's talented midfielder who wasn't quite able to excel as expected for the English Premiere League's Tottenham Hotspur. Look for Paulinho to be a player who can make all the difference in what should be a toughly contested match.
