The 2025 Club World Cup, held in the United States from June 14 to July 13, has delivered far more than spectacular football. It has exposed a decisive advantage: heat adaptation and physical resilience, traits that have favored South American clubs—especially the Brazilians—throughout the tournament.
The American summer, marked by extreme heat and humidity, has become a strategic factor. South American players, either already accustomed to these conditions or early arrivals who acclimatized for weeks, demonstrated a level of endurance that Paris Saint-Germain simply could not match.
The 1–0 victory over the reigning Champions League winners on June 19 at the Rose Bowl was no accident. Igor Jesus scored in the 36th minute, and Botafogo executed a flawless tactical plan that neutralized PSG’s possession and punished every defensive lapse.
According to coach Renato Paiva, it was “a tactical clash”—a product of intensive preparation in Los Angeles after navigating Brazil’s unforgiving December calendar. The results speak clearly: Botafogo tops its group with two wins, leaving PSG searching for answers.
The Heat: A Strategic and Physical Ally
From the beginning, South American teams warned about the weather. FIFA applied hydration protocols and cool-down breaks—introduced in 2014—but the real difference lay in acclimatization.
European squads showed bursts of intensity followed by long drop-offs. Meanwhile, Botafogo, Flamengo, Palmeiras, and others maintained freshness and pressure until the final whistle. Arriving early to train in North American heat has proven decisive.
Botafogo’s victory also reflects deep structural rebuilding since 2022, after the acquisition by John Textor. The club reduced debt, strengthened its roster, and recruited players like Igor Jesus, Barboza, and Freitas as part of a financially sound project.
On the field—under temperatures surpassing 40°C—Botafogo demonstrated both physical and economic superiority over European giants with massive budgets but limited resilience.
The South American Wave Challenging Europe
Botafogo is not an isolated case.
- Flamengo defeated Chelsea 3–1.
- Brazilian clubs collectively scored 14 goals and conceded only four.
- South America remains undefeated in the tournament.
FIFA has already acknowledged the “South American energy” visible across U.S. stadiums and is considering hosting the tournament in Brazil in 2029.
This climate advantage is not a minor technical detail—it is geopolitics on the pitch. Playing in Los Angeles or Dallas in June is not comparable to competing in Manchester or Munich. The body reacts before the mind does.
European clubs arrived with tight schedules, still riding the wave of Champions League fatigue and its media obligations. South American teams, although in the midst of local competitions, sent advance delegations to acclimatize. Botafogo arrived as early as 18 days before its first match.
The result is clear: a team comfortable in hot, heavy air against another battling dehydration and frustration. In these conditions, football is not always defined by tactics or technique—but by lungs.
It Wasn’t Just Botafogo
Fogão’s triumph is part of a broader trend. Flamengo beat Chelsea. Palmeiras challenged Manchester City. Fluminense held Bayern Munich to a draw. All these teams arrived with the same strategy: physical adaptation and competitive focus.
South American football treats the Club World Cup with urgency because it represents its last major international arena. The region no longer consistently wins intercontinental titles, its top talents leave early, and its economies face growing pressure.
In this tournament, however, South America has something Europe cannot buy: necessity. When properly trained, necessity becomes an advantage.
This is why John Textor planned an American-style preseason months in advance. It was a calculated risk—and it paid off.
PSG, Struggling for Explanations
After the defeat, PSG manager Luis Enrique admitted: “The team couldn’t find its rhythm and the heat was a determining factor.” In plain terms: they were cooked alive.
The thermal effect in modern football is unforgiving. FIFA authorized hydration breaks at the 30th minute of each half—just as it did in Qatar. Except this time the heat was not desert-dry; it was heavy California humidity—39°C with 70% humidity.
PSG did not play poorly. They simply failed to play at the pace that Botafogo sustained. In today’s football, where sprinting trumps possession, that difference is decisive.
Could a South American Team Win the Club World Cup?
A question that once seemed impossible—can a South American team win a modern Club World Cup?—no longer feels unrealistic.
With FIFA expanding the format to 32 teams and adopting a full World Cup schedule, the tournament now includes group stages, long travel, and demanding climates. The old December mini-final is gone. This is a real global competition.
And in that environment, heat is the great equalizer—not because it is fair, but because it is uncontrollable.
For decades, football’s key figure was the classic number 10. Later, it was the tactical brain like Xavi or the relentless runner like Kanté. But at the 2025 Club World Cup, the new decisive player is the one who stays standing after minute 70.
Physical preparation and climate adaptation are now critical variables. In both areas, Brazil is far ahead of European football, which continues to believe that air-conditioned training centers can compensate for real-world heat.
Botafogo may not win the tournament. They could fall in the quarterfinals or semifinals. But their victory over PSG proves something essential: South American football still has a voice in global competition—when it prepares with the seriousness the tournament demands.
Heat does not discriminate, but it does punish unprepared teams. And in this Club World Cup, more than ever, talent means little if you are short of oxygen.
