Overview
- Arsenal confirmed Saturday that Karl Hein will join Werder Bremen on a permanent deal in July with the Bundesliga club set to activate a €3 million purchase option, subject to standard regulatory clearance.
- Bremen expect Hein to sign a multi-year contract and to compete for the starting goalkeeper role after Mio Backhaus is strongly linked with a move to SC Freiburg.
- Hein made only two Bundesliga appearances while on loan in 2025/26 and his season ended in March after he required thumb surgery.
- The 24‑year‑old joined Arsenal’s academy from Nõmme United in 2018, made one senior appearance for the club in November 2022, and spent multiple loan spells at Reading and Real Valladolid before the move to Bremen.
- For Hein, the permanent transfer offers a clear path to regular top‑level football; for Arsenal, it is a modest fee recovery and part of a wider summer reshaping of peripheral squad players that followed Jakub Kiwior’s exit.
