Mamelodi Sundowns and Fluminense will compete at Miami's Hard Rock Stadium to secure a spot in the FIFA Club World Cup knockout stages on Wednesday evening.
Group F is finely balanced, with Fluminense tied on four points with Borussia Dortmund, one point above the surprising South African team.
Mamelodi Sundowns claimed victory over Ulsan HD in their first match, gaining an advantage over Fluminense, who played out a 0-0 draw with Dortmund.
Miguel Cardoso's team showcased determination in a 4-3 loss against the Germans, while Fluminense came from behind to defeat Ulsan HD 4-2.
Tricolor, the runners-up in the previous Club World Cup edition, understand that a draw will be sufficient to advance to the round of 16, but their opponents will likely require a win.
Team news
Mamelodi Sundowns forward Lebo Mothiba may have picked up an injury during the defeat to Borussia Dortmund on Saturday and will undergo a late fitness assessment.
Tashreeq Matthews replaced Arthur Sales in the starting XI against the Bundesliga outfit and is expected to retain his spot.
Fluminense will be missing midfielder Otavio and forward Yeferson Soteldo, both ruled out at the beginning of the tournament.
Nonato and Keno, who both found the net as substitutes against Ulsan HD, are anticipated to start, with Everaldo also in contention for another chance in the attack after an impressive cameo.
The stats
Both Fluminense and Borussia Dortmund know that a draw will see them progress to the next round.
A victory is required for Mamelodi Sundowns to advance, while Ulsan HD are already eliminated.
Fluminense have been unbeaten in their last eight matches, scoring at least two goals in six of those games.
After two group stage fixtures, only four teams at the Club World Cup (Bayern Munich, Pachuca, Inter Milan, and Benfica) have attempted more shots than Fluminense.
Mamelodi Sundowns have won just one of their last four matches.
Only three clubs (Boca Juniors, Monterrey, and Auckland City) have registered fewer shots on target than Mamelodi Sundowns in the group stage matches.
Prediction
Considering the thrilling and attacking style displayed by both teams in their recent group matches, another exciting game seems likely.
Mamelodi Sundowns posed a threat to Dortmund with their attacking prowess, although defensive errors cost them dearly.
The South African side's best chance of progression will be to maintain their attacking approach against Fluminense, who displayed defensive vulnerabilities in their previous match.
Fluminense's attacking players were pivotal in breaking down their opponents when the game opened up, particularly Colombian midfielder Arias, who has been influential with three goal contributions in four Club World Cup matches and is a strong candidate to increase his tally from set-pieces and penalties.
