Tournament favourites Brazil face Mexico on Monday in the first last 16 round tie of the day.
Brazil topped their group, however were far from convincing at times.
They claimed seven points from three games, which included victories over Costa Rica and Serbia.
Mexico were lucky to progress in the end, despite stunning Germany in their opening fixture.
A 3-0 defeat to Sweden in their final game meant they needed a favour from South Korea and the Asian nation duly obliged.
The two nations met at the previous World Cup, with Mexico holding Brazil to a goalless draw.
Brazil have a good recent record against Mexico, losing just one of the last six meetings.

Marcelo is set to recover from the mystery issue that forced him off against Serbia on Wednesday.
Danilo is still a major doubt, meaning Fagner is likely to continue to deputise from right-back.
Mexico will be without the banned Hector Moreno, with Hugo Ayala favourite to come in.
Miguel Layun has played in an unfamiliar right wing role at the tournament, but is set to continue.

Brazil (4-3-3): Alisson; Fagner, Miranda, Silva, Marcelo; Casemiro, Paulinho, Coutinho; Willian, Neymar, Gabriel Jesus
