FC Barcelona opened a disciplinary proceeding against goalkeeper Marc-André ter Stegen after he refused to sign a medical report authorizing the club to share his injury details with LaLiga's Medical Commission. This refusal complicated the club's efforts to comply with financial fair play regulations and register new signings. The dispute escalated with Barcelona temporarily stripping Ter Stegen of the team captaincy, a decision made in coordination with the coaching staff, and assigning the captaincy to center-back Ronald Araújo. The conflict drew attention from the German Football Association and professional players' unions, which supported Ter Stegen's legal right to privacy regarding his medical information. Despite Barcelona's firm stance and legal preparations, Ter Stegen later expressed willingness to collaborate and signed the authorization, leading the club to close the disciplinary case and reinstate him as captain. The episode highlighted tensions between the player and the club that had been simmering since the previous season.
