Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
In April 2026, reports indicated FSV Mainz 05 is targeting at least €60 million for the player. This followed a March 2026 report stating Mainz was asking for a minimum of €25 million. A similar figure of 'more than €25 million' was reported as the club's demand in November 2025. The player's Transfermarkt value was consistently cited as €25 million across reports from November 2025 to April 2026. His last completed transfer was from Kashima Antlers to FSV Mainz 05 in July 2024 for a reported fee of €2.5 million.
Our valuation is driven by FSV Mainz 05's escalating asking price for Kaishu Sano, which reportedly rose from a minimum of €25 million to a target of at least €60 million amidst expectations of a bidding war. This range is supported by interest from multiple clubs, including in the Premier League, and the player's long-term contract until 2028, which strengthens the selling club's negotiating position.
