Dortmund face a summer of strengthening, with the team that Edin Terzic guided to the Champions League final already being dismantled. In addition to Terzic himself resigning, Hummels leaving and Marcos Reus retiring, Marius Wolf is out of contract, while permanent transfers for loan signings Jadon Sancho and Ian Maatsen could prove too much to bear financially. It means the club will have to hit the market if they are to compete with Bayer Leverkusen and Bayern Munich in the Bundesliga in 2024-25.
