Swiss Super League giants St. Gallen have officially signed Ghanaian defender Stephan Ambrosius.

Ambrosius has joined St. Gallen on a three-year contract, coming on board as a free agent after his contract with German club Hamburger SV ended.

The Ghanaian defender started his journey with Hamburger in 2012, progressing through the youth teams before breaking into the senior squad.

Last season, the central defender made 18 appearances for Hamburger SV in Bundesliga 2, following his return from a loan stint at Karlsruher SC at the end of the 2022/23 season.

Ambrosius has represented the Ghana national team, the Black Stars, in two friendly matches last year.

At St. Gallen, he will wear jersey number 5 and will join fellow Ghanaian internationals Lawrence Ati-Zigi and Musah Nuhu in the squad.
