Kaishu Sano has been linked with Tottenham Hotspur, and a transfer fee of up to 60 million euros has been discussed. Christian Heidel, the sporting director for Mainz 05, stated that the club is not required to sell Kaishu and can afford to retain him. Heidel added that if Sano stays, many people in the team, the club, and its surroundings will be happy. The sporting director also emphasized that, as is customary at Mainz 05, they must consider an offer if it is exceptionally high.

According to Team Talk, Tottenham are monitoring Kaishu Sano with interest and have been in contact with his representatives.

Tottenham Hotspur have expressed interest in acquiring Mainz midfielder Kaishu Sano during the summer transfer window. On the Last Word on Spurs podcast, Ben Jacobs mentioned that Tottenham admire the 24-year-old midfielder and may consider pursuing him. Jacobs characterized Sano as a very combative number six, with the ability to transition between lines and excel in aerial duels. Furthermore, Sano is noted for his progressive passing and underappreciated attacking skills, which make him a valuable asset in a counterattacking team. Tottenham view him as a potential successor to Yves Bissouma, who is rumored to be on his way out. The prospect of moving to England and competing in the Premier League is appealing to Sano, and Tottenham, having secured a spot in the Champions League, presents an enticing opportunity. The club has appointed a talented manager in Thomas Frank, who could potentially maximize Sano's abilities. A transfer to Tottenham would represent a significant career advancement for Sano, and the club possesses the financial capability to finalize the transaction.
