Before the Academy: Potrero, Baby Fútbol, Futsal, Várzea
The major South American clubs recruit children at nine, ten, or eleven years of age. What these children have done up to that point differs fundamentally from Europe.
Argentina: Potrero and Baby Fútbol
The potrero is the uneven wasteland where Argentine children play football – without coaches, pitch markings, or age brackets. The term has become a symbol of an education that is no formal education at all: children learn because they play, against older kids, with a poor ball, on rough ground. Diego Maradona, Carlos Tevez, and Juan Román Riquelme all described the potrero as their true school.
Alongside this sits baby fútbol: organised leagues for children between roughly five and thirteen, mostly based in neighbourhood clubs, on small pitches, often indoors or on concrete, featuring five to seven players per side. Messi played baby fútbol at Grandoli in Rosario before joining Newell's. The format is similar to futsal: tight spaces, high touch counts, relentless duels, and a fast ball.
The combination – unstructured potrero and small-sided baby fútbol – means that an Argentine child at age ten has logged thousands more hours of ball contact than a European child training in a club since the U9s. Crucially, they have spent those hours without tactical instructions.
Brazil: Futsal and Várzea
In Brazil, the foundation is futsal. The game is ubiquitous in schools and local clubs, and virtually every Brazilian professional of the last thirty years played it as a child: Ronaldinho, Neymar, Vinícius Júnior, Philippe Coutinho. Futsal coaches in Brazil are youth development specialists in the truest sense – teaching technique, feints, and ball control under pressure. The transition to the 11-a-side pitch usually occurs between ages ten and twelve.
Complementing this is várzea, the Brazilian equivalent of the potrero: amateur and street football in suburban neighbourhoods, played on sand, dirt, and concrete. Less romantic than the myth, but very real: the density of informal football in Brazilian metropolitan areas is higher than anywhere in Europe.
What This Means
South American academies take in ten-year-olds who are already complete footballers in their instincts. The academy does not need to teach them how to receive a pass under pressure. It has to teach them how to function within a team. That is an entirely different task from that of a European academy, which enrols eight-year-olds and must teach them both.
This is why asking "How do Boca and River train?" is partly the wrong question. The answer to "Where does this come from?" lies, for the most part, entirely outside structured training.
The Structure: Inferiores and Base
Argentina
Argentine clubs organise their youth setup into inferiores, categorized by birth year from the Novena (roughly U13) up to the Cuarta (roughly U20), with the Reserva sitting directly above. All sides compete in official AFA federation leagues against the inferiores of rival clubs. The competition is intense, public, and heavily result-driven. A Boca vs River clash in the Séptima attracts hundreds of spectators and is analysed in national sports media.
The top clubs maintain a pensión, a boarding house for players recruited from the interior provinces. Argentina is vast, talent is scattered across the country, and moving to Buenos Aires is a genuine migration for a twelve-year-old child. Julián Álvarez arrived at eleven from Calchín, a village of roughly 3,000 residents in Córdoba Province, and grew up in River Plate's pensión. The pensión forms part of the club's soul and is one reason why the emotional bond between players and their club is often far stronger in Argentina than in Europe.
The jump to the first team happens early. Argentine clubs face severe economic pressures and throw prospects into senior action at 17 or 18 because they rely on selling them. While born of financial necessity, it replicates what Benfica do with their B team: competitive men's football for 18-year-olds.
Brazil
Brazilian clubs refer to their youth ranks as the base – spanning age categories from Sub-11 to Sub-20. The primary showcase is the Copa São Paulo de Futebol Júnior (the Copinha), an enormous U20 tournament held every January that is broadcast across the nation, routinely launching breakout talents into senior squads and towards Europe. In addition, clubs contest the national U20 Championship, U17 Championship, and, since 2011, the U20 Copa Libertadores.
Entry points are more accessible than in Argentina. Peneiras – open trial days that attract hundreds of aspiring youngsters – are standard practice in Brazil. Alongside these runs an extensive network of scouts, intermediaries, and agents that intervenes earlier and more aggressively than in Europe. A Brazilian talent often has representation by age 14.
Transfers to Europe are agreed at 16, as soon as the first professional contract can be signed. The physical move takes place at 18, strictly complying with FIFA regulations on international transfers of minors. Vinícius Júnior was sold to Real Madrid in 2017 at 16 and moved in 2018. Endrick was secured by Real Madrid in 2022 and moved in 2024. Estêvão was signed by Chelsea in 2024, completing his move in 2025.
River Plate: La Máquina and the Pensión
River Plate are synonymous with Argentine footballing elegance. The club's identity traces back to their legendary 1940s side – La Máquina – and remains an active philosophy today: technical, combination-heavy football played by individuals with supreme composure on the ball.
The academy trains in Ezeiza, south of Buenos Aires, at the River Camp, sharing the facility with the first team. The pensión forms an integrated part of this training centre.
Notable Graduates: Pablo Aimar, Javier Saviola, Ariel Ortega, Hernán Crespo, Esteban Cambiasso, Gonzalo Higuaín, Radamel Falcao – who joined from Colombia at 15 –, Erik Lamela, Julián Álvarez, Enzo Fernández, Exequiel Palacios, Gonzalo Montiel, Claudio Echeverri, and Franco Mastantuono, who moved to Real Madrid in 2025 at age 18.
What River do differently:
Nationwide talent identification. River maintain a network of scouts across every Argentine province, bringing prospects to Ezeiza at ten or eleven years old. The pensión makes this feasible. Álvarez, Fernández, and Palacios all arrived from the country's interior.
Playing philosophy as an initial filter. River seek players tailored to the La Máquina ethos: technical, sharp, and tactically intelligent. A player whose game relies purely on raw pace or physical robustness will find it far tougher to progress at River than at Boca.
The Gallardo blueprint for pathway integration. Marcelo Gallardo managed River from 2014 to 2022, winning two Copa Libertadores titles – in 2015 and 2018, the latter against Boca in the Madrid final – while consistently promoting academy prospects. Under his guidance, Álvarez, Fernández, Palacios, and Montiel established themselves as key starters before going on to become World champions.
Boca Juniors: Casa Amarilla and the Pressure
Boca Juniors are the cultural counterpoint. Hailing from the dockside barrio of La Boca, the club embody *garra* – relentless grit, fighting spirit, and defiance. La Bombonera is arguably South America's most intense arena, and the sheer pressure it generates directly shapes their youth development.
The youth setup trains at Casa Amarilla, right in the shadow of the stadium, whereas the senior squad operates out of Ezeiza. Boca recognise this geographic separation as a practical drawback.
Notable Graduates: Carlos Tevez, Fernando Gago, Éver Banega, Nicolás Gaitán, Leandro Paredes, Cristian Medina, Exequiel Zeballos, Valentín Barco (who moved to Brighton in 2024), and Aaron Anselmino (sold to Chelsea in 2024). Juan Román Riquelme arrived at 17 from Argentinos Juniors – a borderline graduate, yet the player who defined Boca's footballing identity above all others.
What Boca do differently:
Competition as education. Boca's inferiores play to win. The club view the intimidating cauldron of La Bombonera as something young players must be hardened for – and they achieve this by exposing them to high-stakes pressure early. This stands in complete contrast to the Ajax philosophy and closely mirrors Benfica's environment.
Riquelme's presidential focus. Juan Román Riquelme, the club's greatest icon, assumed the presidency in 2023 and positioned the academy at the heart of the sporting project. Academy players were integrated into the first team earlier and in greater numbers. First-team domestic and continental results dipped during this spell, highlighting how difficult it is to balance youth promotion with silverware at a club of Boca's unrelenting expectations.
Mentality before tactical systems. Boca graduates are rarely defined by a uniform tactical style; instead, they share a distinctive temperament. Tevez and Paredes have little in common stylistically beyond an absolute refusal to shy away from responsibility under extreme pressure. That mental resilience is precisely what Boca cultivate.
Flamengo: Ninho do Urubu
Flamengo boast the largest fanbase in Brazil and, since roughly 2019, the greatest financial power. The club lifted the Copa Libertadores in 2019, 2022, and 2025 – the latter with a 1-0 win over Palmeiras in Lima – making them the first Brazilian club to win four continental titles.
The youth academy trains at the Ninho do Urubu complex in western Rio de Janeiro, alongside the senior squad. In 2019, ten academy players tragically lost their lives in a fire at the club dormitories. The tragedy left a permanent mark on the club and triggered an overdue national reckoning regarding accommodation standards for young athletes across Brazil.
Notable Graduates: Zico, Júnior, Adriano, Vinícius Júnior, Lucas Paquetá, Reinier, Matheus França, João Gomes, Wesley, and Lorran. Vinícius remains their defining modern success story: sold to Real Madrid at 16 for approximately €45 million, he has developed into one of the world's most decisive players.
What Flamengo do differently:
Financial strength as a retention mechanism. Unlike most South American sides, Flamengo can retain prime talent and come close to matching European wage packages. Their 2025 Libertadores-winning squad combined high-profile European returnees – Jorginho, Alex Sandro, Danilo – with homegrown starters. This blend of elite recruitment and academy production is unmatched across South America.
Promoting coaches from within the academy. Filipe Luís, the former Brazil international, took charge of Flamengo's U17s and U20s from 2023, stepped up to the senior job in 2024, and won the Copa Libertadores in 2025. That progression from youth coach to senior manager within the same club mirrors Marco Rose at Salzburg or Bruno Lage at Benfica – a pathway that was previously rare in Brazilian football.
Strategic investment into the base. Under president Luiz Eduardo Baptista, Flamengo restructured their youth department from 2025 onwards to close the operational gap on Palmeiras. Their investment bore immediate fruit, winning back-to-back U20 Copa Libertadores titles in 2024 and 2025.
Palmeiras: South America's Most Productive Academy
Palmeiras established themselves as the dominant academy in South America throughout the 2020s. Figures reported by Brazilian media in January 2026 illustrate their reach: since 2020, 51 academy graduates have made their senior first-team debuts. Over that window, the club generated more than 1.5 billion reais – roughly €250 million – purely from academy player sales. Headline departures include: Estêvão to Chelsea for up to €61.5 million with add-ons, Endrick to Real Madrid for up to €60 million, and Vitor Reis to Manchester City for around €37 million – the highest fee ever commanded by a Brazilian club for a defender.
The architect of this system is João Paulo Sampaio, head of the academy base since 2015. Under his guidance, Palmeiras tripled their coaching staff and expanded their scouting presence across almost the entire country. Palmeiras lifted the Copinha in 2022 and 2023, alongside the U20 Copa Libertadores in 2022.
What Palmeiras do differently:
Youth development as the core business model. Sampaio stated the objective clearly in interviews: turn Palmeiras into one of the top five talent producers in world football, measured by senior debuts and transfer revenues. The club report investing around 200 million reais into the base, recouping close to one billion in returns. This is Benfica's academy model fuelled by Brazil's exceptional talent pool.
Unbroken pathway under Abel Ferreira. The Portuguese manager, in charge since 2020, delivered back-to-back Copa Libertadores titles in 2020 and 2021 while continually trusting academy graduates: Endrick, Luis Guilherme, Estêvão, Vitor Reis, and Allan. Having a Portuguese head coach grounded in European structural development oversee Palmeiras' most prolific era is no coincidence. The tactical and operational bridge between Portuguese and Brazilian football has never been stronger.
Early contracts, maximum leverage. Palmeiras tie down prospects with professional contracts and hefty buyout clauses the moment they turn 16, allowing the club to negotiate with European giants from a position of absolute strength. Club directors revealed they rejected bids of 30, 35, and 40 million for Estêvão when he was just 15, holding out to secure 45 million plus performance bonuses twelve months later.
System over folklore. Palmeiras' rise is the least romantic story in this overview. There is no reliance on potrero mythologies or street-football nostalgia. It is driven by an elite academy director, tripling the coaching staff, building a national scouting grid, and executing a ruthless transfer strategy. It is the modern European academy structure operating on Brazilian soil – and it works.
The Criticism
Romance disguises structural decline. The potrero and várzea are genuine cultural cornerstones, but they are rapidly disappearing. South American cities are losing open urban spaces, children spend more time indoors, and informal pickup football is diminishing. Academies recognise this and are attempting to recreate what previously developed naturally through structured futsal and small-sided programmes. Whether these artificial environments can fully replicate the original remains an open debate.
The talent drain weakens domestic leagues. South American clubs are forced to sell their brightest prospects between ages 16 and 19. Domestic competitions are demonstrably weaker on the pitch than they should be. Flamengo and Palmeiras can partly cushion this loss through domestic financial power; Boca and River simply cannot.
An unregulated agent market. In Brazil, the influence of intermediaries over 14-year-olds presents a serious challenge that football authorities struggle to regulate. Agencies, clubs, and families negotiate over minors in an aggressive, open marketplace.
Excessive result pressure on young players. Argentine inferiores play for win bonuses, league tables, and under intense media scrutiny. While this breeds players who can handle hostility, it also burns out promising youngsters who are not psychologically equipped for such pressure at 14.
Player safeguarding and welfare. The tragic 2019 fire at Ninho do Urubu revealed that accommodation standards for youth players in South America do not always match the basic safety regulations taken for granted across Europe. Any honest assessment of the region's development pipeline must acknowledge this reality.
A lack of formalised curriculum. As with most academies featured in this series, there is no standardised manual. What European coaches can borrow are general training principles and structural frameworks, rather than a step-by-step drill book.
Application: What You Can Take Away
This section reflects our coaching interpretation.
The lesson from South America is arguably the most challenging of this series, because it suggests that the most critical development occurs before formal coaching begins. Even so, the principles are fully transferable to your own sessions.
Introduce Unstructured "Potrero Time"
Free play without coach interference is not lost training time — it aligns directly with the principles of letting children play. In fact, it is the most valuable phase of your session. Set aside twenty minutes at the start of your youth training: throw out the balls, set up small goals, and let them play. Do not intervene. Do not keep score. Do not offer corrections. That is the potrero environment your players no longer experience on the street.
Futsal in Winter, Small-Sided Games in Summer
The core Brazilian lesson: congested spaces demand elite ball manipulation. In winter, favour futsal over traditional indoor football drills played with side boards. Outdoors, base your work on 3v3 and 4v4 formats on compact pitches using mini goals. Use these formats not merely as a warm-up, but as the foundational core of your training sessions up to U11 level.
Pit Older Players Against Younger Ones
The potrero naturally mixes age brackets. A ten-year-old playing against thirteen-year-olds learns to use their body and shield the ball under duress out of pure survival, or they will simply never touch the ball. Running a mixed game format across two age groups once a week develops composure and spatial awareness faster than any isolated 1v1 drill.
Calibrate Pressure Deliberately
The Argentine takeaway, applied sensibly: players must be exposed to situations where something tangible is on the line. Run training tournaments with visible standings, organise penalty shootouts in front of the entire team, or set up matches where the losing side collects the equipment. Do not do it every week, but incorporate it on a regular basis.
Learn from Palmeiras: Structure Trumps Folklore
If you hold a leadership role at your club, Palmeiras' success offers a clear roadmap: they tripled their youth staff and established a comprehensive scouting grid. There is no South American magic at play – it is deliberate investment in people. A grassroots club cannot triple its budget, but it can ensure that every single youth team is staffed by two dedicated coaches rather than one.
Adopt the "Pensión" Mentality of Belonging
River and Boca secure exceptional loyalty because they foster deep emotional connection. A player who grows up feeling part of a club community rarely wants to leave. For grassroots clubs, this means making the club about more than just training sessions: team meals, club tournaments, and attending senior team matches together. It costs very little, yet creates a bond that keeps players involved far longer than any training drill ever could.
Key Takeaways
- South American academies enrol ten-year-olds who are already refined footballers – moulded by the potrero, baby fútbol, futsal, and várzea. The answer to where their intelligence comes from lies almost entirely in their pre-academy playing volume.
- Argentine inferiores are public and fiercely result-oriented. The pensión creates lifelong club affinity for players from across the country. First-team progression happens early, driven by economic necessity.
- River develop for La Máquina; Boca develop for La Bombonera. Two contrasting identities, two distinct player profiles.
- Flamengo unite player development with elite financial muscle, winning the 2025 Copa Libertadores under their former youth coach Filipe Luís.
- Palmeiras are the most prolific academy in South America – not through romantic folklore, but through structured methodology: tripled coaching staff, nationwide scouting, and a clear sales model.
- Unstructured street football is fading, early player sales drain domestic quality, and the youth agent landscape presents serious challenges.
- Key transferable lessons: unsupervised free play, futsal and small-sided games, mixed-age matches, calibrated competitive pressure, investing in coaching staff, and building genuine club belonging.
The single most impactful drill from this region is not a drill at all: put the balls out, set up the goals, and remain silent for twenty minutes. Coach OS helps you plan the other 70 minutes with precision.
