Teun Koopmeiners

In August 2026, reports linked Napoli to a potential deal around the player's book value of approximately €33 million, while his Transfermarkt value was cited as €14 million. Throughout spring and summer 2026, Juventus's asking price was consistently reported at €30 million amid interest from multiple English and Italian clubs. Earlier, in January 2026, Galatasaray was reportedly willing to pay €27 million, with other reports mentioning a loan-to-buy option of around €25 million. His completed transfer from Atalanta to Juventus in August 2024 was for a reported €51.3 million, with some sources citing figures up to €60 million including bonuses.

Our valuation is driven by Juventus's consistently reported asking price of €30 million throughout 2026, a figure set to avoid a capital loss on their significant 2024 investment. This price point is tempered by Teun Koopmeiners's subsequent underperformance and the lack of concrete offers, with earlier reported interest from Galatasaray suggesting a lower floor around €25-27 million. The final estimate reflects a likely compromise between the club's desired fee and the market's actual interest.
