"FC Barcelona will initiate disciplinary proceedings against its goalkeeper Marc-André ter Stegen, who is currently injured. A spokesperson for the Spanish football champions confirmed a report by the newspaper "Mundo Deportivo" to the news agency dpa. The background to the measure is that the German international goalkeeper is refusing to authorise the club to forward his injury report to the league's medical commission.
Ter Stegen recently underwent another operation on his back. The club expects him to be out of action for four months or longer. In this case, Barça could use 80 per cent of the salary of the absent player to register a new player in accordance with the financial fair play rules applicable in Spain. Interestingly, the player in question is Joan García, whom the Catalans signed as their new number one from Espanyol Barcelona in the summer.
In a social media post, Ter Stegen himself spoke of a three-month absence, angering the financially struggling club. Barcelona already had considerable problems registering ex-Leipzig player Dani Olmo last season.
The 33-year-old goalkeeper still has a well-paid contract at Barcelona until 2028. However, the club would like to get the German international keeper off the payroll. Until the new injury, there had also been a number of well-known interested parties such as Manchester City, Manchester United, Chelsea FC, Inter Milan, AC Milan, Juventus Turin, Galatasaray Istanbul and AS Monaco. This has been cancelled by the operation.
The player's medical data is confidential, so his consent is required for disclosure. The club is aware of the player's right, but also recognises its obligations towards the employer.“
