Just before the hour mark in the match against Augsburg, with the familiar roar of 81,365 fans filling the stadium, 18‑year‑old defender Luca Reggiani found the back of the net for Borussia Dortmund. The sheer elation on his face was instantly relayed to academy director Paul Schaffran, who watched the celebration from the club's training centre.
"When our youngsters break into the first team, it lifts everyone's spirits," Schaffran told Sky Sports. The conversation took place in a Liverpool hotel ahead of a development fixture, and it was clear that Reggiani is part of a broader pattern at the club. Another 18‑year‑old Italian, Samuele Inacio, made his Bundesliga debut against Bayern Munich in February and quickly proved he could cope with the demands of top‑flight football. "He has already shown he belongs at this level," Schaffran noted.
Then there is 16‑year‑old prodigy Mathis Albert, who earned his first senior appearance against Freiburg last Sunday. And 17‑year‑old Mussa Kaba is knocking on the door of a debut, having been with Dortmund since he was eleven. "I have known Mussa since he was eleven and I rate him very highly," Schaffran said.
The three youngsters who have arrived from outside the club – Inacio from Atalanta and Reggiani from Sassuolo – illustrate Dortmund's dual‑track philosophy. "We aim to develop home‑grown talent from the ground up, but we also need the external pillars to strengthen the pipeline," Schaffran explained. "Players need to see a clear pathway, and we provide that." The notion of Dortmund as a finishing school for elite talent is not new.
The arrivals of Erling Haaland and Jude Bellingham a few years ago underscored the club's reputation for accelerating the growth of promising players. Yet recent pressure to deliver results forced a rethink in senior‑team recruitment, prompting the club to look even younger for its next breakthroughs. This shift placed a heavier burden on Schaffran and his staff to refine the development process.
"Our mindset at the academy has undergone a complete overhaul," he said. "We used to concentrate on winning at every youth level, but a victory at under‑17 level means nothing if the player does not become a Bundesliga professional." The new doctrine flips the old approach on its head.
"We now deliberately give our youngsters the toughest challenges possible at youth level," Schaffran continued. "By exposing them to high‑intensity, physically demanding situations early, we make the transition to senior football smoother. It's a massive change in our thinking." According to the academy director, Dortmund currently fields the youngest under‑17 and under‑19 squads in Germany, as well as the youngest side competing in the Premier League International Cup.
The club does not expect to win those tournaments; the objective is developmental exposure. "We are not doing this because it looks good on paper," Schaffran emphasized. "We over‑challenge our players because prolonged under‑stimulation hampers adaptation and growth." He elaborated on the importance of adaptation: "The game is getting faster, more physical and increasingly complex. Players must learn to adjust quickly.
Each adaptation phase may reduce immediate impact on the pitch, but it dramatically raises long‑term development potential." A key innovation supporting this philosophy is the introduction of bio‑banding, which uses ultrasound scans to determine the true skeletal age of academy players. This scientific approach revealed that six years ago the academy composition was heavily skewed: 35% early developers, 60% average, and only 5% late developers. The imbalance reflected a bias toward early‑maturing bodies rather than pure talent.
"The biggest lesson from bio‑banding was for our coaches and scouts," Schaffran said. "It forced them to reassess how they evaluate players. A 14‑year‑old who is physically dominant but technically limited is no longer automatically favoured over a smaller, more talented peer who may develop later." He cited a specific case of a player who would have been dismissed under the old system because he was slower than his peers.
Given the chance to progress at his own pace, that player now has a realistic prospect of reaching the senior level. "Instead of imposing quotas, we focused on education and awareness," Schaffran explained. "This year we achieved a balanced distribution: 15% early developers, 70% average, and 15% late developers." Balancing individual development with team performance can be tricky. When Inacio and Albert excelled with the under‑19s, they were promptly promoted to higher age groups to face tougher opposition.
Albert's versatility has been particularly noteworthy; he featured in Dortmund's Club World Cup squad, represented the United States at the Under‑17 World Cup, and has already played for the under‑19s and under‑23s across domestic and international competitions. "He constantly adapts to new environments," Schaffran observed.
Such promotions can weaken a youth side, as the most talented players leave. "If we only cared about winning at youth level, we would keep them," Schaffran admitted. "But our metric is development, not trophies." The alignment between the academy and the first team has been reinforced under the leadership of former academy chief Thomas Ricken, now a key decision‑maker for the senior squad.
Schaffran is regularly invited to first‑team squad planning meetings, ensuring a seamless dialogue about promising youngsters. Ricken himself has been instrumental in recruiting many of the current academy prospects, smoothing the transition pathway. When Schaffran saw Reggiani celebrate his goal with the under‑12 to under‑15 groups back at the academy, his pride was palpable. "Luca returned to the academy to share his joy with the younger kids," he said, underscoring the club's culture of shared success.
In summary, Dortmund's academy overhaul hinges on three pillars: a willingness to challenge players beyond their comfort zones, the use of scientific tools like bio‑banding to eliminate age‑related bias, and a clear, collaborative link between youth and senior coaching staffs. By prioritising long‑term growth over short‑term results, the club hopes to maintain its reputation as a conveyor belt of elite talent, feeding the first team with players who are not only technically skilled but also mentally resilient and physically prepared for the rigors of modern football.
