According to Bild, Fortuna Düsseldorf is interested in acquiring Andreas Müller from Karlsruher SC. Andreas Müller, 26, is Fortuna Düsseldorf's intended main number-6 midfielder, but his current club, Karlsruher SC, has not yet accepted the transfer conditions proposed by manager Samir Arabi. Fortuna has already signed Marcel Benger as a low-cost option, which also addresses the possibility of them failing to acquire their main target. It is reported that the club hopes the deal for Müller will be completed quickly. The German midfielder joined Karlsruher SC in July 2025 and has a market value of €800k, according to Transfermarkt.
