Karlsruher SC sign Madagascar-France defender Sandro Tremoulet from Radnik

Madagascar-France centre-back Sandro Tremoulet has joined German club Karlsruher SC from Serbian side Radnik, strengthening the 2. Bundesliga team’s defensive options.

Tremoulet, 26, completed the move on 11 August 2026 after a season with Radnik in the Super liga Srbije. The left-footed defender was born in Sete, France, on 18 November 1999 and stands 1.90m tall.

He moves to Karlsruher after previously playing for Radnik during the 2025-26 season. Before that, Tremoulet had a spell without a club before joining the Serbian side in July 2025.

The defender’s career has included time in France, Belgium, Armenia and Serbia. He joined Ararat Yerevan in January 2025 after leaving Belgian club RFC Seraing, having previously moved to Seraing from French side FC Sete 34 in July 2022.

Tremoulet began his senior career with French clubs including FU Narbonne, Vannes and Le Cres FC. He moved between Narbonne and Vannes during the 2019-20 and 2020-21 seasons before joining FC Sete 34 in July 2021.

His arrival gives Karlsruher a centre-back with experience across several European leagues and adds a left-footed option to the club’s defensive department. The player is eligible to represent both Madagascar and France, reflecting his dual nationality.

Karlsruher compete in Germany’s 2. Bundesliga, while Radnik play in Serbia’s top division. Tremoulet’s latest move therefore takes him into a new national league after his season in Serbian football.

The transfer is the latest stage of a career that has taken Tremoulet from lower-league French football to clubs in Belgium, Armenia and Serbia. He now continues that journey with Karlsruher SC, where he has joined the squad for the 2026-27 campaign.
