Just before the hour mark in the match against Augsburg, in front of the familiar sea of 81,365 fans, 18‑year‑old defender Luca Reggiani found the net for Borussia Dortmund. The sheer elation on his face echoed back 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 the spirit of everyone involved," Schaffran told Sky Sports. As the academy chief, he explained that Reggiani’s breakthrough is part of a broader pattern that the club is deliberately fostering.
Another 18‑year‑old Italian, Samuele Inacio, made his Bundesliga debut against Bayern Munich in February, and the club’s prodigy Mathis Albert, only 16, earned his first senior appearance versus Freiburg last Sunday. Seventeen‑year‑old Mussa Kaba is also on the brink of a debut.
"He has been with us since he was 11 and I rate him very highly," Schaffran said, highlighting the club’s confidence in its youth pipeline. Three of these talents arrived from outside the club – Inacio from Atalanta and Reggiani from Sassuolo – illustrating Dortmund’s dual strategy: nurture home‑grown players while also recruiting promising foreigners early enough to shape them in the Dortmund way. "The average centre‑back in Italy is over 30, so an 18‑year‑old like Luca would struggle to get minutes there," Schaffran noted, underscoring why the Ruhr side can offer faster pathways for young defenders.
The notion of Dortmund as a finishing school is not new. Stars such as Erling Haaland and Jude Bellingham used the club as a springboard to global stardom. However, recent pressure to deliver results forced the club to rethink its recruitment philosophy for the senior squad, prompting a sharper focus on developing talent from within.
Faced with competition from other top clubs, Dortmund decided to go even younger, hoping to uncover hidden gems before rivals can snap them up. This shift placed a greater burden on Schaffran’s staff to refine these players more quickly. The academy’s mindset, according to Schaffran, has undergone a radical overhaul.
"We changed our vision, our style of how we want to develop players," he explained. "In the past we were primarily focused on winning at youth level, but a victory at under‑17 means nothing if the player does not become a Bundesliga professional." He continued: "Now we deliberately give our youngsters the toughest challenges possible. By exposing them to high‑intensity, physically demanding situations early, we make the transition to senior football smoother. It’s a complete reversal of our previous approach." Dortmund now boasts the youngest under‑17 and under‑19 squads in Germany, as well as the youngest contingent in the Premier League International Cup.
They are not there to chase trophies; the aim is developmental exposure. "We are not doing it because it looks good to be the youngest," Schaffran said. "We over‑challenge them so they learn to adapt quickly.
If you keep them comfortable for too long they stagnate." He elaborated on the philosophy: "Adaptation inevitably reduces efficiency in the short term – you won’t dominate every game while you’re learning. But the long‑term developmental payoff is massive.
The faster a player learns to adjust to new tactical demands, physical intensity, and complexity, the better equipped they will be for the senior game." A key tool in this new strategy is bio‑banding. By using ultrasound scans to determine each player’s true skeletal age, Dortmund can place youngsters in groups that reflect their physical maturity rather than just their calendar age. Six years ago, the academy’s composition was heavily skewed: 35 % early developers, 60 % average, and only 5 % late developers. The new data revealed that such a distribution was more a product of scouting bias than genuine talent identification.
"The biggest lesson from bio‑banding wasn’t for the players, it was for our coaches and scouts," Schaffran said. "They now evaluate prospects with a far more nuanced lens.
A 14‑year‑old who is being out‑muscled today but shows technical brilliance is no longer dismissed outright." He cited an anonymous player who would have been rejected under the old system because he was slower than his peers. Given time to develop at his natural pace, that player now has a realistic chance of progressing through the ranks. Rather than imposing quotas, Dortmund opted for education.
The result this season is a balanced spread: roughly 15 % early developers, 70 % average, and 15 % late developers. This equilibrium reflects a commitment to individual growth rather than rigid statistical targets. The approach does have short‑term costs for the youth teams. When Inacio and Albert performed exceptionally for the under‑19s, they were promoted to higher age groups, leaving a gap in the squad.
Albert, in particular, has shown remarkable adaptability, having featured for Dortmund’s Club World Cup roster, the United States U‑17 World Cup team, and now the under‑19 and under‑23 sides across domestic and international competitions. "He thrives in varied environments and keeps stepping up," Schaffran observed. Admittedly, losing top performers can be painful for the coaches. "If we only cared about winning at youth level, we would keep them," Schaffran admitted.
"Our metric is development, not trophies." The pathway to the senior side remains open thanks to former academy chief Rudi Ricken, now a key decision‑maker for the first team. Schaffran works closely with Ricken, attending squad planning meetings and discussing promising youngsters. Ricken’s involvement in recruiting many of these players has streamlined their integration into the senior setup.
Seeing Reggiani’s jubilant reaction after his goal against Augsburg was a proud moment for Schaffran. "Luca returned to the academy and celebrated with the under‑12‑to‑15 groups," he said, emphasizing how the success of one player reverberates throughout the whole system. In summary, Dortmund’s academy has reinvented itself as a high‑intensity development engine.
By deliberately challenging its youngest talents, employing scientific tools like bio‑banding, and maintaining a clear line of communication between youth and senior staff, the club aims to produce a steady stream of Bundesliga‑ready players. The conveyor belt of talent is humming again, and the future looks bright for both the club and the young athletes who aspire to wear the famous black‑yellow shirt.
