West Ham defender Amber Tysiak has joined German side Union Berlin.
The 25-year-old made 49 appearances for West Ham after joining in 2023 and signed a three-and-a-half-year contract extension in January 2025.
Union Berlin are believed to have paid a fee of £150,000, plus add-ons, for the Belgium international.
The German club went professional in 2023 and earned back-to-back promotions to reach the Frauen-Bundesliga for the first time this year.
