Leonardo Balerdi

In spring 2026, reports indicated Bayer Leverkusen had a proposal of €25 million plus bonuses accepted by Marseille, though the player refused the move. Around the same time, Marseille's asking price was reported to be €30 million in April 2026, with a general market value estimate between €20-€25 million in May 2026. Throughout 2025, various reports linked him to other clubs: Juventus was reportedly interested at €25 million, AS Roma was linked with offers around €20 million, and Leeds United was considering a bid of approximately €24 million (£20m). During that period, Marseille's asking price was cited as being significantly higher, between €40 million and €45 million. His last completed transfer was from Borussia Dortmund to Marseille in July 2021 for a reported €11 million.

Our valuation is driven by the very recent and strong report of an agreed deal between Olympique Marseille and Bayer Leverkusen for €25 million plus bonuses. This figure is corroborated by consistent valuations from other interested clubs in the €20-€25 million range. We've set the top of our range at Marseille's most recently reported asking price of €30 million, acknowledging their negotiating position for Leonardo Balerdi.
