West Ham defender Amber Tysiak has made the move to German Bundesliga side Union Berlin. The transfer sees the 21-year-old center-back departing the Women's Super League club after a spell in London. No terms of the deal were officially disclosed by either club in the announcement.

This switch reunites Tysiak with former West Ham manager Marcel Kaelin, who now leads the defensive setup in Berlin. For Union Berlin, securing the German international addresses a key need for experience in their backline. It represents a significant step up in competition for the player.

Tysiak joined West Ham in 2022 and made 29 appearances for the Hammers. She now faces competition for a starting spot against established defenders like Kathrin Hendrich. Her primary challenge will be adapting to the tactical demands of the German top flight.
