Rigobert Song's men sit third in Group F with one point from two outings meaning that anything less than a victory in their final group game would see them suffer an early exit.
Tite's men, on the other hand, have successfully booked their place in the last 16 and just need to avoid defeat in this one to qualify as group winners.
