If you were anywhere near Rio de Janeiro on November 4, 2023, you felt it. The air was thick. Not just with the usual Brazilian humidity, but with a tension that only South American football can cook up. On one side, you had Boca Juniors, the Argentine giants chasing a record-equaling seventh title. On the other, Fluminense, the "Big Four" club from Rio that had never actually tasted continental glory.
It was a clash of identities. Boca brought their "Mystique"—that weird, unquantifiable ability to win even when they aren't the better team. Fluminense brought "Dinizismo," a chaotic, beautiful, position-less style of play that makes European coaches scratch their heads.
Honestly, it wasn't just a game. It was a 120-minute war.
The Night Fluminense Finally Broke the Curse
For years, people talked about Fluminense as the biggest club in South America without a Libertadores trophy. They came close in 2008, losing on penalties in this same stadium. The ghosts were everywhere.
Then came Germán Cano.
The man is a machine. He scored 13 goals in that 2023 campaign. Think about that. That's more than the entire Boca Juniors squad combined during the tournament. In the 36th minute, he did what he does: found a pocket of space and swept the ball home. The Maracanã didn't just cheer; it exhaled.
But you can never count out Boca. They were toothless for most of the first half, but they've got this annoying habit of staying alive. In the 72nd minute, Luis Advíncula, the Peruvian right-back who basically carried Boca’s offense that season, cut inside and unleashed a left-footed rocket. 1-1. Suddenly, the Brazilian fans were staring at those 2008 ghosts again.
The Hero and the Anti-Hero: John Kennedy
If you're writing a script for Boca Juniors vs Fluminense, you can't make up a character like John Kennedy.

He came on as a sub. He looked like he was playing at a different speed. In the 99th minute, during extra time, the ball sat up for him on the edge of the box. He didn't just hit it; he deleted it. A volley so clean it felt like the stadium shifted an inch to the left.
Then, the chaos.
Kennedy, already on a yellow, jumped into the crowd to celebrate with the fans. It’s the kind of thing every fan loves and every referee hates. Wilmar Roldán had no choice. Second yellow. Red card. Fluminense had the lead, but they were down to ten men with 20 minutes left.
Why This Matchup Still Matters Today
People look at the stats and see a 2-1 win for Fluminense, but the Boca Juniors vs Fluminense rivalry is about the shift in power. For a long time, Argentine clubs dominated. Now? Brazil has won five straight Libertadores titles.
Boca’s loss was more than just a missed trophy. It was a reality check. They reached the final without winning a single knockout game in 90 minutes. They relied on Sergio Romero saving penalties, round after round. When it came down to actually outplaying a team on the grass, they couldn't do it.

The drama didn't end with Kennedy's red card, either. Frank Fabra, Boca’s veteran left-back, decided to slap Nino in the middle of a VAR review. It was one of those "what are you doing?" moments. Straight red. The numerical advantage was gone, and with it, Boca’s last real chance to equalize.
The Numbers That Tell the Story
- Germán Cano's 13 goals: A record for a player in a single edition of the tournament this century.
- Boca's Final Drought: This was their third straight final loss (2012, 2018, 2023).
- Possession: Fluminense held 53%, typical of Fernando Diniz's style, forcing Boca to chase.
What Most People Get Wrong About the Final
A lot of casual fans think Boca was "robbed" or that the home-field advantage at the Maracanã was unfair. While it’s true Fluminense plays there, CONMEBOL picks the final venue years in advance. It was a fluke of the draw that Fluminense made it to their own backyard.
Also, the "Boca Mystique" is often used to cover up tactical flaws. Jorge Almirón, Boca's coach at the time, was heavily criticized for his substitutions. Taking off Valentín Barco and Edinson Cavani when the team needed a goal felt like a surrender.
Basically, Fluminense didn't just win because they were at home. They won because they had a clear plan and a striker who couldn't stop scoring.
Moving Forward: Actionable Insights for Fans
If you're looking to follow these teams or understand where they go from here, keep an eye on a few key things:
- Watch the "Dinizismo" evolution: Fernando Diniz's style is polarizing. Whether he's at Fluminense or elsewhere, his teams will always produce high-risk, high-reward football that is a tactical goldmine for students of the game.
- Boca's Rebuilding Phase: Boca has since moved on from Almirón. They are trying to find a balance between their historical grit and the need for modern, creative play. Look at how they integrate young talents from their academy, like Equi Fernández, who was a standout even in the loss.
- The Brazil-Argentina Gap: Until Argentine clubs can match the financial muscle of Brazilian giants like Flamengo, Palmeiras, and Fluminense, expect more finals to look like this one—Boca fighting with heart while the Brazilians play with the better roster.
The 2023 final was a turning point. It cemented Fluminense as a continental power and left Boca searching for an identity that isn't just "waiting for penalties." It was ugly, it was beautiful, and it was exactly what South American football is supposed to be.
