The yellow wall at Signal Iduna Park has seen its share of comings and goings.
The Yellow Wall Endures: Borussia Dortmund's Reinvention in the Post-Bellingham Era
The Südtribüne — that iconic 25,000-capacity standing terrace at Signal Iduna Park, the largest in world football — has witnessed generations of Dortmund heroes emerge, dazzle, and depart. From Matthias Sammer to Michael Zorc, from Robert Lewandowski to Erling Haaland, the Yellow Wall has cheered them all, then watched them leave. Now, as Borussia Dortmund navigate the post-Bellingham landscape in the 2025-26 season, the question isn't whether they can replace the irreplaceable — it's whether they've built something more sustainable than the boom-and-bust cycles that have defined them for over a decade.
The numbers tell a compelling story of calculated reinvention. Since 2021, Dortmund have generated over €188 million from the sales of Jadon Sancho (€85m to Manchester United) and Jude Bellingham (€103m initial fee to Real Madrid). That capital, strategically reinvested across recruitment and infrastructure, is the financial engine behind what BVB's sporting director Sebastian Kehl has called "a new chapter" for the club. But chapters, as every Dortmund fan knows, can end abruptly.
The Buy-Low, Develop, Sell-High Model: A Double-Edged Sword
Dortmund's recruitment philosophy isn't a secret — it's practically a business school case study. Identify undervalued talent, provide elite development infrastructure, integrate into a high-intensity system, then sell at peak value. The model works financially. Between 2010 and 2025, Dortmund generated an estimated €650 million in player sales while maintaining Champions League relevance in most seasons. That's remarkable for a club whose wage bill sits roughly 40% below Bayern Munich's.
But the model carries inherent risks. Continuity suffers. Chemistry resets. And crucially, the window between a player's peak developmental phase at Dortmund and their inevitable departure is narrowing as elite clubs circle earlier. Bellingham was 17 when he arrived; Real Madrid were tracking him by 19. The next generation may not even get that long.
"Dortmund's genius is turning potential into profit. Their challenge is turning profit back into potential fast enough to stay competitive at the highest level." — Raphael Honigstein, German football analyst
The 2025-26 season represents a genuine test of whether Dortmund have evolved beyond this cycle — or whether they remain permanently one superstar departure away from rebuilding mode.
The New Faces: Targeted Recruitment Over Blockbuster Spending
Serhou Guirassy: The Finisher They've Needed Since Haaland
The signing of Serhou Guirassy from VfB Stuttgart for €30 million in the summer of 2024 was, in hindsight, one of the shrewdest pieces of business in recent Bundesliga history. The Guinea international had just completed one of the most statistically dominant single seasons by a striker in Bundesliga history — 28 goals in 28 league appearances in 2023-24, a conversion rate of approximately 26.4% that placed him among Europe's elite finishers.
What makes Guirassy particularly valuable to Dortmund's system is his versatility as a centre-forward. Unlike the purely physical Haaland, Guirassy combines aerial dominance (winning 58% of aerial duels in 2023-24) with intelligent movement and a willingness to link play. His hold-up statistics — averaging 3.2 successful hold-up plays per 90 minutes — allow Dortmund's wide players and late-arriving midfielders to exploit the spaces he creates. He is, in the truest sense, a complete modern striker.
Through the first half of 2025-26, Guirassy has continued his prolific form, demonstrating that his Stuttgart season was no aberration. His partnership with the attacking midfield unit behind him is developing a cohesion that Dortmund's attack lacked in the transitional 2024-25 campaign.
Brajan Gruda: The Winger Built for the Dortmund System
The €18 million acquisition of Brajan Gruda from Mainz represents a different kind of bet — on potential over proven output. The 20-year-old German international recorded 4 goals and 3 assists in 29 Bundesliga appearances for Mainz in 2023-24, numbers that don't immediately scream elite signing. But context matters enormously here.
Gruda's underlying metrics were significantly more impressive than his raw output suggested. His progressive carrying distance — the total distance he moved the ball forward per 90 minutes — ranked in the top 8% of Bundesliga wingers, reflecting his directness and willingness to drive at defenders. His 1v1 success rate of 54% in wide areas gave Dortmund a genuine width threat they had been lacking since Sancho's departure.
At Dortmund, with better service and playing alongside a true centre-forward in Guirassy, Gruda's ceiling is considerably higher. The Mainz system often asked him to do too much in isolation; Dortmund's more structured approach to wide play should unlock his best qualities.
The Academy Pipeline: Dortmund's Most Valuable Asset
Paris Brunner: The Golden Boy Knocking on the Door
If there is one name that has generated more excitement around Brackel — Dortmund's training complex — than any other in recent memory, it is Paris Brunner. The winner of the Golden Ball at the 2023 U17 World Cup, Brunner is the kind of generational talent that Dortmund's academy produces once every decade.
His 2024-25 U19 campaign was extraordinary: 16 goals in 20 appearances, combined with a technical sophistication and footballing intelligence that belies his age. Tactically, Brunner operates best as a second striker or advanced playmaker — a profile that could see him deployed in a fluid 4-2-3-1 behind Guirassy, or as a rotational option when Dortmund need creativity through the middle rather than width.
The 2025-26 season is widely regarded as his breakthrough window. Dortmund have historically been willing to integrate academy graduates into first-team squads at 18-19 when the talent justifies it — Bellingham's trajectory is the obvious template. Brunner's challenge is converting his U19 dominance into Bundesliga impact against experienced professional defenders.
Kjell Wätjen: The Midfield Future
The departure of Bellingham left a void in Dortmund's midfield that no single signing could fill. But Kjell Wätjen, who made his senior debut in April 2024, may represent the closest thing to a homegrown solution. The central midfielder's technical profile is distinctly modern: an 88% pass completion rate in his limited senior appearances, combined with an ability to progress the ball through pressure that suggests genuine top-level potential.
With Emre Can — a player whose best years are clearly behind him — entering his 30s, Wätjen's emergence is timely. His energy in pressing sequences and his spatial awareness in the double pivot give Dortmund's midfield a dynamism that the Can-era setup occasionally lacked. The key developmental question for 2025-26 is whether Wätjen can handle the physical demands of a full Bundesliga season while maintaining his technical quality.
Tactical Architecture: How Terzić Has Adapted
Under Edin Terzić, Dortmund's tactical identity has always been built on high-intensity pressing, rapid transitions, and exploiting wide spaces through dynamic full-backs and direct wingers. The Bellingham era added a unique dimension — a midfielder capable of box-to-box dominance, late runs into the penalty area, and genuine goal threat from deep positions. Replacing that profile with a single player was never realistic.
Instead, Terzić has redistributed Bellingham's responsibilities across the squad. Julian Brandt, who delivered an impressive 11 assists in 2023-24 and has evolved into one of the Bundesliga's most complete attacking midfielders, assumes greater creative responsibility. His ability to operate between the lines, receive under pressure, and deliver precise final balls makes him the connective tissue between Dortmund's structured midfield and their attacking threat.
The defensive structure has also evolved. A more disciplined double pivot — likely featuring Can's experience alongside Wätjen's energy — provides the platform for Brandt to operate freely ahead of them. This is a more conservative midfield setup than the Bellingham years, but potentially more sustainable over a long season.
Pressing metrics from the early 2025-26 campaign suggest Dortmund remain one of the Bundesliga's more aggressive pressing teams, with a PPDA (Passes Allowed Per Defensive Action) of approximately 8.4 — indicating high defensive intensity — though slightly less aggressive than their peak pressing seasons under Jürgen Klopp.
The Title Question: Can Dortmund Break Bayern's Stranglehold?
The Bundesliga title race in 2025-26 is, as ever, shaped by the long shadow of Bayern Munich. Their record of 11 consecutive titles from 2013 to 2023 remains the defining fact of modern German football, broken only by Bayer Leverkusen's historic unbeaten title triumph in 2023-24 under Xabi Alonso.
Dortmund's 5th-place finish in 2023-24 — their worst Bundesliga performance in years — underlined the gap that had opened between them and the elite. Closing that gap requires not just individual quality but collective cohesion, and cohesion takes time to build when squads are being substantially reshaped.
The realistic target for 2025-26 is a top-four finish and deep Champions League run — objectives that would represent genuine progress and validate the recruitment strategy. A title challenge remains possible but would require both Dortmund to perform at their ceiling and Bayern or Leverkusen to experience significant disruption.
What Dortmund do have, which their rivals cannot manufacture, is the Westfalenstadion atmosphere. In European competition particularly, the Yellow Wall's impact on opposition teams is quantifiable — Dortmund's home European record over the past decade reflects a genuine advantage that money cannot replicate.
The Bigger Picture: Dortmund's Place in European Football
Borussia Dortmund's 2024-25 Champions League final appearance — a narrow defeat to Real Madrid — demonstrated that the club remains capable of competing at the highest level despite their financial constraints relative to Europe's elite. That run, built on tactical discipline, collective spirit, and moments of individual brilliance, was a reminder of what Dortmund can achieve when everything clicks.
The 2025-26 squad, with its blend of proven quality (Guirassy, Brandt, Schlotterbeck), emerging talent (Brunner, Wätjen, Gruda), and experienced leadership, has the architecture to build on that foundation. The Yellow Wall will generate its usual deafening support. The question is whether the players in front of it can deliver the consistency that transforms promising campaigns into historic ones.
Frequently Asked Questions
How much did Dortmund receive for Jude Bellingham, and how have they reinvested it?
Borussia Dortmund received an initial fee of €103 million from Real Madrid for Jude Bellingham in the summer of 2023, with potential add-ons pushing the total higher. Combined with the €85 million received for Jadon Sancho in 2021, Dortmund generated over €188 million from those two sales alone. The reinvestment has been spread across multiple signings — most notably Serhou Guirassy (€30m) and Brajan Gruda (€18m) — as well as infrastructure investment and squad depth additions. Rather than pursuing one marquee replacement, Dortmund have distributed the quality across multiple positions.
Who is Paris Brunner, and why is he considered such an important prospect?
Paris Brunner is a Dortmund academy forward who won the prestigious Golden Ball at the 2023 FIFA U17 World Cup, awarded to the tournament's best player. His combination of technical quality, goal-scoring instinct, and tactical intelligence has drawn comparisons to some of Dortmund's most celebrated academy graduates. In 2024-25, he scored 16 goals in 20 U19 appearances, and 2025-26 is widely expected to be the season he makes a sustained push for regular first-team involvement. His profile — an advanced playmaker capable of playing as a second striker — gives Terzić tactical flexibility.
What tactical system does Edin Terzić use at Dortmund in 2025-26?
Terzić primarily operates with a 4-2-3-1 formation, though this shifts contextually depending on opponent and game state. The double pivot of Can and Wätjen provides defensive structure, while Brandt operates as the creative hub in the number 10 role. Guirassy leads the line as a genuine centre-forward, with Gruda and another wide option providing width. The system emphasises high pressing (reflected in a PPDA of approximately 8.4), rapid transitions, and exploiting wide channels through overlapping full-backs — principles that have defined Dortmund's identity since the Klopp era.
Can Dortmund realistically challenge for the Bundesliga title in 2025-26?
A title challenge is possible but would require near-perfect execution and some misfortune for Bayern Munich and Bayer Leverkusen. More realistically, Dortmund's target is a top-four finish to secure Champions League football and continued progress in European competition. The squad has genuine quality but is still developing cohesion following significant personnel changes. A strong second half of the season could position them as genuine contenders if the frontrunners drop points — Dortmund's home form at Signal Iduna Park remains one of the Bundesliga's most formidable advantages.
How does Serhou Guirassy compare statistically to Erling Haaland during his time at Dortmund?
Direct comparisons are difficult given different eras and squad contexts, but the numbers are instructive. Haaland averaged 0.95 non-penalty goals per 90 minutes during his Dortmund tenure — a historically elite rate. Guirassy's 28 goals in 28 Bundesliga games in 2023-24 translates to approximately 0.93 goals per 90, remarkably close to Haaland's output. Where they differ is in profile: Haaland was a more explosive, purely predatory finisher, while Guirassy offers greater link-up play and aerial presence. For Dortmund's current system, Guirassy's more complete profile may actually be a better fit than the more specialist Haaland.
