You’ve probably seen the scorelines popping up on your feed lately, and honestly, if you aren't following the drama between Fluminense vs Gualberto Villarroel San José, you’re missing out on one of the weirdest David-and-Goliath stories in South American football. We aren't just talking about a couple of random games. This is a clash of identities. On one side, you have the Brazilian giants, the "Tricolor" from Rio, and on the other, a Bolivian underdog that most people couldn't even point to on a map two years ago.
It’s been a wild ride in the 2025 Copa Sudamericana.
Most fans expected Fluminense to just walk over GV San José. And for a while, they did. But football is rarely that simple. The trip from the beaches of Rio de Janeiro to the thin, punishing air of the Bolivian Andes changes things. It changes players. It changes the ball's physics. Basically, it turns "guaranteed" wins into absolute nightmares.

What Actually Happened at the Maracanã
When GV San José traveled to Brazil in April 2025, it was a slaughter. Let's be real. Fluminense was in one of those moods where everything clicked. They walked away with a 5-0 victory that felt like a training session. Everaldo was the star of that particular show, bagging two goals before the halftime whistle even blew.
The stats were brutal:
- Everaldo: 2 goals (21' and 44')
- Kevin Serna: 1 goal (59')
- Germán Cano: 2 goals (73' and 79')
Samuel Xavier and Keno were carving up the wings like they were playing against a youth team. At that point, the narrative was set. Fluminense was the powerhouse, and GV San José was just happy to be there. But then, the return leg happened.
The Altitude Trap: Fluminense vs Gualberto Villarroel San José in Oruro
If you haven't seen a game played at the Estadio Hernando Siles in La Paz, it’s hard to describe. The air is so thin you can practically see the players gasping for breath by the 20th minute. Fluminense arrived in May 2025 thinking they had this in the bag. They were wrong.
GV San José turned into a completely different beast at home. They weren't the nervous, disorganized side we saw at the Maracanã. Instead, they were fast, aggressive, and clearly used to the 3,600-meter elevation. Fluminense’s passing, which usually looks like clockwork, started falling apart. Thiago Santos was slipping, Ganso looked like he was running through chest-deep water, and even the legendary Fábio had to make some desperate saves early on.
Then came the 69th minute.
Moises Calero found a gap in the defense and slotted the ball past Vitor Eudes (who was starting that night). The stadium went mental. That 1-0 win for Gualberto Villarroel San José wasn't just a fluke result; it was a statement. It showed that in South American football, historical prestige doesn't mean a thing when you can't breathe.
Who Are These Guys? Understanding GV San José
Look, Gualberto Villarroel San José (often just called GV San José) isn't your typical "old guard" club. They were founded back in 1968, but their rise to the top of Bolivian football and into continental competitions like the Sudamericana is relatively fresh. They represent Oruro, a city that lives and breathes football but has often lived in the shadow of the big clubs from La Paz.
The roster is a mix of local Bolivian talent and some gritty Argentine imports. You've got guys like:
- Joel López Pissano: The creative engine in midfield.
- Bruno Poveda: The goalkeeper who had to stand on his head to keep Fluminense out.
- Dico Roca: A left-back who provides way more offensive pressure than you'd expect.
They play a 4-4-2 that can feel like a brick wall when they’re defending a lead. Against Fluminense, they didn't try to out-skill the Brazilians. They out-ran them. They out-lasted them. Honestly, it was smart.

The Fluminense Perspective: A Lesson in Humility
For Fluminense, these matches were a wake-up call. Under their management in 2025, the team has been trying to balance the aging legs of legends like Renato Augusto and Ganso with younger, faster talents like Facundo Bernal and Kevin Serna.
In the 5-0 win, the veterans looked like geniuses. Every pass was perfect. In the 1-0 loss, they looked their age.
This is the central tension of Fluminense vs Gualberto Villarroel San José. It’s a battle between the "Beautiful Game" (Jogo Bonito) and the "Hard Game." Flu wants to possess the ball, keep it at 60% or 70%, and slowly dismantle you. GV San José wants to make the game ugly, interrupt the rhythm, and wait for that one moment where a defender's lungs give out.
Why Group F Became the "Group of Death"
Nobody expected Group F to be this tight. Usually, the Brazilian or Argentine team runs away with it, and everyone else fights for second. But because GV San José managed to take points off Fluminense, the whole table got messy.
By the end of the group stage in late 2025, Fluminense still finished on top with 13 points, but they didn't escape unscathed. GV San José only finished with 4 points total, but 3 of those points came from that historic night against the Tricolor. They might have finished last in the group, but they became the "giant killers" that everyone in Rio was talking about for weeks.
Practical Insights for the Next Season
If you're a bettor or just a hardcore fan looking toward the 2026 season, there are a few things you have to take away from these matches.
First, never trust a Brazilian team at altitude, no matter how many goals they scored in the first leg. The "Altitude Factor" is a real, measurable statistic that wipes out about 15-20% of a visiting team's passing accuracy.
Second, watch Kevin Serna. Even when Fluminense was struggling in Bolivia, he was the only one who seemed to have the engine to keep pushing. He’s going to be a massive asset for them as they move into the 2026 Copa Libertadores, where they are already seeded in Pot 1 alongside teams like Flamengo and Palmeiras.
Finally, keep an eye on the Bolivian league. GV San José proved that the gap between the mid-tier teams in Bolivia and the top-tier teams in Brazil is closing, especially when the conditions aren't perfect.
The saga of Fluminense vs Gualberto Villarroel San José is a reminder of why we love the Sudamericana. It’s messy. It’s exhausting. It’s unpredictable. If you want to stay ahead of the curve for the 2026 season, start tracking the injury reports for Fluminense’s older midfielders now—it’s going to be the deciding factor in whether they can handle another deep run in South America.
Check the latest 2026 Copa Libertadores schedule to see if these two might cross paths again in the knockout stages if GV San José can pull off another miracle in their domestic league.
