In the coming summer, a decision would have to be made regarding 19-year-old Turkish-German centre-back Mertcan Ayhan. Either he is sold for a significant fee, as his contract would then only run for one more year, or both sides intend to continue their cooperation, either by clause or by another extension. His contract also includes an option until 2029. The player with one cap for Türkiye U21 has a current market value of €8.00m, according to Transfermarkt.
