Stuttgart moved early to secure Stiller’s future, offering an improved extension in early 2025 that runs until 2028 and elevates him to one of the club’s top earners. The contract includes a release clause estimated around €40m, though it does not activate until summer 2026. Crucially, Stuttgart also hold an internal option to buy out the clause for around €2m, meaning they could remove it at any time and negotiate freely with interested clubs.
Despite this, Stuttgart’s internal valuation sits much higher. Reports in Germany suggest the club would demand at least €50m if approached before 2026, especially given the global interest. Wohlgemuth acknowledges the persistent speculation but insists the club remain calm: “That’s part of the entertainment we have to cover. But there’s nothing concrete. He can concentrate fully on Stuttgart.”
Stiller, meanwhile, remains committed to Stuttgart’s project, but has also made no secret of his ambition to take the next step when the timing is right. With major clubs preparing summer strategies, the coming transfer window may be decisive. If Madrid, United or Liverpool formalise their interest, Stuttgart will face a pivotal decision over one of Germany’s most coveted midfielders.
