Kaishu Sano

In September 2026, reports mentioned a last-minute Premier League offer of approximately €30 million, with a separate link to Crystal Palace for a potential £30 million (approx. €35 million) deal. Throughout summer 2026, Mainz 05's asking price was consistently reported at €50-60 million amid interest from clubs like Liverpool, Newcastle, and Arsenal, with Liverpool reportedly prepared to offer up to €60 million in July. Earlier valuations were lower, with a minimum asking price of €25 million reported in March 2026. His last completed transfer was in July 2024 from Kashima Antlers to FSV Mainz 05 for a reported €2.5 million.

Our valuation for Kaishu Sano is shaped by the conflict between FSV Mainz 05's consistent asking price of €50-60 million and a late transfer window bid of around €30-35 million from the Premier League. Given the player's long contract until 2028, Mainz holds a strong negotiating position, but the reported offer suggests the market is not currently willing to meet their highest demands. The estimate reflects a likely compromise between these two figures.
