Overview
- Heidenheim recalled Kevin Müller to its training squad and had him undergo fitness and medical checks after his loan at Schalke ended, leaving the transfer unresolved.
- The Heidenheim board says a free transfer is unacceptable for economic reasons and is seeking a reported low six‑figure fee before allowing Müller to leave.
- Schalke wants Müller without paying a fee so he can serve as an experienced backup to Loris Karius, whose own contract was recently extended to 2027.
- Müller remains under contract with Heidenheim until summer 2027 and made four appearances for Schalke during their 2025/26 promotion run.
- If the clubs cannot agree on compensation, Heidenheim will plan personnel changes for the goalkeeper position and the transfer could collapse, though a deal remains possible if a fee is negotiated.
