Barcelona’s Karim Adeyemi signing marks rare low‐margin sale for Borussia Dortmund

Barcelona’s capture of Karim Adeyemi has broken with one of Borussia Dortmund’s most established transfer traditions, with the German club accepting a deal that delivers only a minimal financial return compared with their recent big-money sales.

The Spanish club confirmed on Thursday that Adeyemi, 24, has joined from Borussia Dortmund for an initial €22m, with a further €7m in performance-related add-ons, taking the total potential value of the transfer to €29m.

According to Spanish newspaper Mundo Deportivo, Dortmund chose to cash in with a year remaining on Adeyemi’s contract rather than risk losing him for nothing in 12 months’ time. However, the figures mean the Bundesliga side have not generated the sizeable profit that has become their hallmark in the transfer market.

Dortmund paid €30m to sign Adeyemi from Red Bull Salzburg in the summer of 2022. Even if all the add-ons due from Barcelona are triggered, the overall package of €29m falls short of that outlay, leaving Dortmund effectively limiting their losses rather than banking a surplus.

The deal therefore stands out as an exception in a decade-long strategy that has seen Dortmund build a reputation as one of Europe’s most astute talent developers and sellers, regularly turning emerging players into record-breaking transfers.

Dembele sets benchmark for Dortmund sales

The transfer of Ousmane Dembele remains Dortmund’s most spectacular piece of business.

The French winger arrived from Rennes in 2016 for just €15m, before moving to Barcelona a year later in a deal worth €135m including bonuses. That single transaction brought Dortmund an estimated €120m profit within 12 months.

Bellingham, Sancho and Pulisic underline model

Jude Bellingham followed a similar trajectory. Dortmund signed the midfielder from Birmingham City in the summer of 2020 for £29m. Three seasons later, he joined Real Madrid for £127m, generating a profit for the German club of close to £98m.

Jadon Sancho also embodied Dortmund’s approach. Recruited from Manchester City for around €10m, he was sold to Manchester United two years later for more than eight times that amount, underlining the club’s ability to buy low and sell high at the peak of a player’s value.

Christian Pulisic’s story reinforced that pattern. Spotted by Dortmund at the age of 16 and brought into their academy in 2015, the American forward later moved to Chelsea for €64m, adding another lucrative exit to the club’s portfolio.

Aubameyang, Haaland and Gittens add to profit list

Pierre-Emerick Aubameyang joined Dortmund from Saint-Etienne in 2013 for €13m. Four years later, Arsenal paid €63m for the striker, leaving Dortmund with a €50m net gain on the Gabon international.

Erling Haaland, signed from Red Bull Salzburg in 2019 for €22m, also delivered a considerable return despite the presence of a release clause. Manchester City activated that clause in 2023, paying €60m and handing Dortmund a profit of €38m.

Jamie Bynoe-Gittens serves as another illustration of the club’s business model. The English winger arrived from Manchester City in 2020 on a free transfer and was sold to Chelsea in 2025 for €56m, meaning virtually the entire fee counted as profit.

Mkhitaryan and Gotze complete lucrative catalogue

Dortmund paid €25m to bring Henrikh Mkhitaryan from Shakhtar Donetsk in 2013. Three seasons later the Armenian playmaker joined Manchester United for €42m, earning Dortmund a further €17m margin.

In the same year, Bayern Munich activated the release clause in Mario Gotze’s contract, paying €37m to secure the Germany international. That amount translated into a straight €37m profit for Dortmund on a player who would go on to score the winning goal in the 2014 World Cup final.

Adeyemi deal breaks with familiar formula

Against that backdrop, Adeyemi’s switch to Barcelona represents a clear departure from Dortmund’s usual transfer outcomes.

While moving the forward on a year before his contract expired aligns with standard economic logic, the club has not realised the substantial gains that have characterised its most famous departures. Instead, Adeyemi’s transfer sits as one of the most notable exceptions in Dortmund’s extensive record of turning developing talents into major financial windfalls.
