St. Gallen defender Cyrill May will spend the rest of this season in the Challenge League. The two clubs announced on Monday that FC Rapperswil-Jona are loaning the 19-year-old Swiss centre-back until June 2027. At FCRJ, it is expected that May will get more match practice. In St. Gallen, he had recently only featured for the U21s. Alessandro Ciarrocchi, sporting director of FC Rapperswil-Jona, is pleased with the signing. According to Ciarrocchi, with Cyrill, they are gaining a very interesting player for their defense. He said that despite his young age, May already brings valuable experience from the Super League and has shown at FC St. Gallen what potential he has. Ciarrocchi also stated that with his height and dynamism, he is a centre-back who fits their requirements profile very well, and that the move gives him the opportunity to gain further valuable match practice and to continue to develop as a player. May, who has three caps for Switzerland's U21 team, joined St. Gallen in May 2025 and his contract is due to expire in June 2030. Transfermarkt currently estimates his market value to be €3.50M.
