Borussia Dortmund has identified 18-year-old attacking midfielder Konstantinos Karetsas as a future 100-million-euro transfer target, according to a report by Fussball Transfers citing Sport Bild. The German club is moving back to its core strategy of signing elite global prospects, echoing the development paths of former stars such as Robert Lewandowski, Ousmane Dembélé, Jude Bellingham, and Erling Haaland.
Internal Expectations and Market Potential for Karetsas
Club executives at Borussia Dortmund view the young Greek international as a prospect capable of reaching a nine-figure market valuation. According to the reported internal assessments, the club believes Karetsas can generate massive financial returns upon a future departure, mirroring previous record-breaking sales.
Historically, only two player departures have crossed the 100-million-euro threshold in Borussia Dortmund’s history: Ousmane Dembélé’s 148-million-euro transfer to FC Barcelona and Jude Bellingham’s 127-million-euro move to Real Madrid. While club leadership aims to operate regularly in those financial brackets once again, genuinely lucrative departures have decreased in frequency in recent years.

Individual Development Plans Under Coach Niko Kovac
To accelerate his transition to senior football and the tactical demands of manager Niko Kovac, Borussia Dortmund has assigned specific personal support to the teenager. Video analyst Roderick van der Ham, who arrived from Liverpool over the summer, works closely with Karetsas on a daily basis.
The specialized coaching staff aims to speed up the player’s adaptation to the club’s desired playing style, ensuring his development path aligns with the high competitive standards of the Bundesliga.
