Karl Hein, Arsenal, Werder Bremen, Jakub Kiwior
23 May 2026
Arsenal confirmed goalkeeper Karl Hein will join Werder Bremen permanently in July, making him their second confirmed transfer exit of the summer. The move follows Jakub Kiwior’s permanent switch to Porto earlier this month.
Hein joined Arsenal’s academy in 2018 but struggled to earn senior chances, spending last season on loan in Germany. Arsenal thanked him for his contribution, while the transfer gives the goalkeeper a clearer route to regular football.
