Mio Backhaus, a 22-year-old German-Japanese U21 national goalkeeper with 5 caps for the team, is on the list of several clubs, including Bayer Leverkusen. Werder Bremen could sell him in the summer to generate needed income. In addition to Leverkusen, SC Freiburg, Brighton & Hove Albion, Newcastle United, Inter, and AC Mailand are also reportedly interested. According to 'DeichStube', Borussia Dortmund has also focused on the goalkeeper and recently made inquiries. Backhaus is under contract with Werder Bremen until 2028. His current Transfermarkt market value is €12.00m, an increase from a reported valuation of €2 million in June 2025; a contract extension signed at that time also reportedly included a high release clause.
