Brighton and Brentford are locked in a competition to sign Kaishu Sano, the midfielder currently playing for Mainz, according to TEAMtalk. The Bundesliga club are anticipating a transfer fee between €50million and €60million – up to £51.9million – for the 25-year-old, who joined them from Kashima Antlers in 2024 for €2.5million.
Sano has become a key performer for Mainz, making 34 Bundesliga appearances this season and earning the nickname ‘Iron Man’ due to his consistent work rate. Sources indicate the player has a strong desire to move to the Premier League, with both Brighton and Brentford identified as leading contenders for his signature. Mainz have already begun identifying potential replacements, signalling their preparation for a likely sale.
Brighton are reportedly drawn to Sano’s profile as an ideal fit for their high-pressing, technically proficient midfield. The club have a proven track record of identifying and recruiting undervalued talent capable of succeeding in the Premier League. Brentford, meanwhile, are seeking to strengthen their midfield options and have been closely monitoring Sano’s progress, with German sources suggesting he is a high priority target.
The Japan international’s market value has risen significantly since his move to Mainz, and a sale would represent a substantial profit for the Bundesliga club, potentially breaking their current transfer record of £25million. Sano’s composure in possession, defensive capabilities, and stamina make him a versatile option for Premier League clubs. While other teams have shown broader interest, Brighton and Brentford are currently at the forefront of the chase. A bidding war is anticipated, though further Premier League enquiries are possible as the transfer window approaches.
