Karl Hein (Arsenal/Werder Bremen)
August 2025
Arsenal confirmed goalkeeper Karl Hein has joined Werder Bremen on loan. The Estonia international, who impressed at Valladolid last season, will compete for minutes behind Mio Backhaus as he looks to continue his development in Germany. Hein, signed by Arsenal in 2018 from Nomme United, has previously had loans at Reading and Valladolid but has yet to feature in the Premier League. Arsenal believe Bremen offers a competitive platform for Hein to gain top-flight European experience.
