Just before the hour‑mark in the match against Augsburg, with the familiar roar of 81,365 fans echoing through the stadium, 18‑year‑old defender Luca Reggiani found the back of the net for Borussia Dortmund. The sheer delight on his face was instantly relayed back to the club’s academy, where director Paul Schaffran watched the celebration on a screen at the training centre. "When our youngsters break into the first team, it lifts the spirit of everyone involved," Schaffran told Sky Sports. As the academy director, he has witnessed a clear shift in the club’s approach, and Reggiani’s goal is just one illustration of a broader trend.
Another 18‑year‑old Italian, Samuele Inacio, made his Bundesliga debut against Bayern Munich in February, and the club’s staff were quick to praise his readiness. Likewise, prodigious 16‑year‑old Mathis Albert earned his first‑team debut versus Freiburg last Sunday, while 17‑year‑old Mussa Kaba is on the cusp of a similar breakthrough. "Mussa has been with us since he was 11 and I hold him in very high regard," Schaffran explained.
The three youngsters were not home‑grown; they were recruited into the academy from elsewhere. "Our philosophy is to develop players from the ground up, but we also need external talent to complement our internal pipeline," he added.
"The key is that they see a clear pathway to the senior side." Inacio arrived from Atalanta, while Reggiani was signed from Sassuolo. Schaffran pointed out that in Italy, centre‑backs typically reach their peak in their early thirties, making it difficult for an 18‑year‑old defender to secure regular minutes at the highest level.
Dortmund, by contrast, offers a faster route to senior football. The notion of Dortmund as a "finishing school" is not new.
The club has already propelled stars such as Erling Haaland and Jude Bellingham into the spotlight. However, recent pressure to deliver results has forced a reassessment of first‑team recruitment, prompting the club to look even younger for hidden gems. This shift places additional responsibility on Schaffran and his staff to refine and accelerate the development of these prospects.
"We have completely overhauled our vision and the way we nurture talent," Schaffran said during a recent interview at the team’s hotel in Liverpool, ahead of a development match. "In the past, the focus was heavily weighted toward winning at every youth level. But a victory at under‑17 level means little if the player does not evolve into a Bundesliga‑ready professional." He continued, "Our new methodology is the opposite of what we practiced before.
We deliberately expose our youngsters to the toughest challenges possible at youth level. The idea is that when they finally reach the senior stage, the transition will be smoother because they have already been tested under pressure. It represents a massive paradigm shift for us." According to Schaffran, Dortmund now fields the youngest under‑17 and under‑19 squads in Germany, and they also field the youngest side in the Premier League International Cup.
The club does not expect to win that competition; the aim is purely developmental. "It is intentional," he emphasized. "We are not doing this just to claim the title of 'youngest team.' The purpose is to over‑challenge our players so they learn to adapt quickly. If we keep them comfortable for too long, they will stagnate and never reach their full potential." He elaborated on the philosophy of constant adaptation: "The modern game is getting faster, more physical and increasingly complex.
Players must learn to adjust to new tactical demands, higher intensity and different physical requirements. Each adaptation period may reduce immediate effectiveness, but it dramatically boosts long‑term growth." A crucial tool in this new strategy has been the implementation of bio‑banding. By using ultrasound technology to determine each player's true skeletal age, Dortmund can place athletes in groups that match their physical maturity rather than their chronological age.
This approach revealed that, six years ago, 35 % of the academy were early developers, 60 % fell within the normal range, and fewer than five per cent were late developers – a distribution heavily skewed by bias rather than genuine talent identification. "The biggest insight from bio‑banding wasn’t for the players, but for our coaches and scouts," Schaffran explained. "It forced them to reassess how they evaluated talent. Previously, a player who dominated his age group would automatically be earmarked for promotion.
Now we understand that a late‑maturing player who may be physically outmatched today could blossom into a star tomorrow." He cited an anonymous example of a youngster who would have been dismissed under the old system because he was slower than his peers. Given time to develop at his own pace, the player now shows promise of reaching the top level. "Instead of imposing quotas, we focused on education and awareness," Schaffran said.
"This season we finally achieved a balanced mix: roughly 15 % early developers, 70 % normal, 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 the next level.
Albert, in particular, demonstrated remarkable adaptability, having featured for Dortmund’s squad at the Club World Cup, represented the United States at the Under‑17 World Cup, and played across the under‑19 and under‑23 teams both domestically and abroad. "He thrives in varied environments and constantly steps up," Schaffran noted.
Admittedly, losing top performers can make the youth sides less competitive. "If we only cared about winning at youth level, we would keep them there," 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 Michael Ricken, who now sits on the senior‑team decision‑making board.
Schaffran regularly attends first‑team squad planning meetings, ensuring that promising youngsters are on the radar of the senior coaching staff. Ricken’s involvement in recruiting many of these players has smoothed the pathway from academy to senior football. The emotional payoff of this system was evident when Schaffran saw Reggiani’s jubilant reaction after his goal against Augsburg. "Luca returned to the academy and celebrated with the under‑12 to under‑15 groups the next day," Schaffran said with pride.
The sight underscored the club’s renewed belief that a well‑structured, challenge‑driven academy can continually feed talent into the first team. In summary, Borussia Dortmund has deliberately re‑engineered its youth development model. By prioritising early exposure to high‑intensity competition, employing scientific methods like bio‑banding to tailor player groups, and fostering a close partnership between academy staff and senior management, the club aims to produce not just winners at youth level, but fully‑fledged Bundesliga professionals.
The results are already visible in the form of teenage debuts, and the long‑term expectation is a steady flow of home‑grown talent that can sustain Dortmund’s competitive ambitions for years to come.
