According to Team Talk, a potential move to England for Kaishu Sano is motivated by financial incentives and a competitive step up. While there were earlier links to Bundesliga side Eintracht Frankfurt, a move to England now appears more probable due to the financial and competitive factors.

Bild reports that Eintracht Frankfurt are seriously considering a move for 24-year-old Kaishu Sano. The publication also states the Japanese midfielder is a high priority for their number six position. Sano transferred to Mainz from Kashima Antlers in 2024 for 2.5 million euros and has played every minute of the current Bundesliga season. Bild reports that a stay at Mainz is not likely, as Sano wishes to advance his career soon. It is uncertain whether that will be in Frankfurt. Sano, who has played for the national team ten times, has a contract with Mainz until 2028. Bild suggests that Mainz would demand more than 25 million euros for the player, a fee that is contingent on the club avoiding relegation. The report from Bild also indicates that a transfer might only be feasible for Eintracht Frankfurt if Hugo Larsson leaves the club for a high multi-million sum. According to Transfermarkt, the player's current market value is €25.00m. He was also linked with Tottenham Hotspur in the past.
