Kaishu Sano

In March 2026, reports indicated Mainz was asking for a minimum of €25 million, with the player's Transfermarkt value also listed at €25 million. Similarly, in November 2025, it was reported that Mainz would demand more than €25 million, a figure again matching his Transfermarkt value at the time. The available data also shows his completed transfer from Kashima Antlers to FSV Mainz 05 in July 2024 for a fee of €2.5 million.

Our valuation is driven by multiple consistent reports from late 2025 and early 2026 stating that FSV Mainz 05's asking price for Kaishu Sano is a minimum of, or more than, €25 million. This figure is supported by his key player status, strong performance in the Bundesliga, and significant interest from multiple clubs in Germany and the Premier League. The valuation reflects a substantial appreciation from his €2.5 million transfer fee in 2024.
