Jonathan Clauss

In September 2025, reports on the failed Bayer Leverkusen transfer detailed a negotiation where Nice's asking price allegedly dropped from an initial €20 million to a final €15 million. Leverkusen's bids reportedly rose to a final offer of €8 million plus €4 million in bonuses, with other reports citing a total package of €12 million or a €7.5 million offer. In August 2025, Nice's demand was reported to be around €8 million. Juventus's interest in July 2025 was reportedly valued between €7 million and €10 million. Throughout 2025, his Transfermarkt value was consistently cited at €5 million. His last completed transfer was from Marseille to Nice in July 2024 for €5 million.

Our valuation is driven by the extensive but ultimately unsuccessful transfer negotiations for Jonathan Clauss between OGC Nice and Bayer Leverkusen in late 2025. Reports indicate a gap between Leverkusen's final offer, reportedly around €8-12 million including bonuses, and Nice's asking price, which was said to be €15 million. Considering the player's age, his public desire to leave, and his recent €5 million transfer fee in July 2024, a compromise figure seems most realistic.
