Regular player in England and for Belgium 

The 25-year-old Tysiak took her first steps in women's football at KRC Genk in 2016, having played mainly in boys' teams til then. She finally made her debut in the Belgian top flight, making her first 15 appearances for Genk in the 2019/20 season. At the end of the season, she moved to league rivals Oud-Heverlee Leuven, where she quickly established herself as a key player and consequently made her debut for the Belgian senior national team in 2021. Tysiak has played alongside Union striker Hannah Eurlings at both Leuven and the Red Flames. 

After 53 appearances in two and a half years, Tysiak made the move to West Ham United in the English Women's Super League in January 2023 where she made four appearances before establishing herself as a regular the following season. Since then, she became an integral part of the Hammers' central defence, playing 52 competitive games, 48 of them in the starting lineup. 

Tysiak is also a regular in the Belgian national team. Since her debut in 2021, she has 45 caps, scoring five goals. Together with Eurlings, she represented Belgium at the 2025 European Championship, playing the full 90 minutes in all three group matches.
