Goals from Neymar and Roberto Firmino were enough to see Brazil through to the quarter-finals of the World Cup at Mexico's expense after a performance which brought as many questions as answers.
The five-time winners dominated the match and could have scored more but were never totally convincing, only making the game safe only once Mexico piled numbers forward in the final minutes of the game.
Neymar put the final touch to a fine team move early in the second half before Firmino profited from Neymar's run to add a second late on.
Brazil will now go on to play the winner of Tuesday's clash between Belgium and Japan, with the odds heavily stacked towards the former.
But what did we learn from the game that got Brazil there?
