Group A's two undefeated sides meet on Tuesday in a match that could end up deciding who tops the group when all is said and done. Three points for either team would guarantee their place in the Round of 16, if Cameroon and Croatia play to a draw on Wednesday.
The host nation Brazil weren't spectacular in their opener against Croatia, but they won, and that's all that matters. There were also plenty of positives for Luiz Felipe Scolari's side. Brazil's star attack Neymar will of course start, but he'll have to be careful after picking up a yellow card in the first match. Another card would mean Neymar would miss the final group stage match.
Mexico played very well against Cameroon, despite the deceiving 1-0 storyline. El Tri had two goals incorrectly disallowed, but they'll nonetheless be full of belief in their ability to get forward on the attack.
Fun fact to impress your friends: this is the same stadium where Mexico and Brazil played in the 2013 Confederations Cup. A Seleção won that match 2-0.
