Former Real Madrid goalkeeper Iker Casillas addressed accusations that he leaked team lineups during Jose Mourinho's final season in a new Netflix documentary released on August 11. The docuseries revisited the turbulent atmosphere inside the Real Madrid dressing room, where Casillas faced quiet suspicion of acting as an internal mole providing starting lineups to the press before matches.

In the documentary, Mourinho described how his relationship with the team fell apart during that final campaign. Mourinho said players had grown tired of him as a leader, adding that he was equally fed up with the squad and the press under heavy daily pressure. When Real Madrid president Florentino Perez tried to persuade him to stay by arguing that easier success lay ahead while Barcelona declined, Mourinho replied that he wanted to leave because he felt his tenure at the club was finished.
Dressing Room Breakdown
Former squad member Sami Khedira, who now works as a technical collaborator for Mourinho in his second managerial spell at Real Madrid, offered detailed insight into the treatment of Casillas. Khedira said Casillas was a Real Madrid legend loved by supporters, yet Mourinho benched him, stopped speaking to him, and criticized him in the media. Khedira stated that this hostile treatment transformed the dressing room into a hell.
Khedira added that the fallout fractured Mourinho's relationship with several key figures, including Cristiano Ronaldo and Spanish squad members. Because those senior players were central to team morale, Khedira explained that the fractured relationships ultimately poisoned the entire dressing room environment.
The turning point that broke the relationship beyond repair was a phone call Casillas made to Barcelona midfielder Xavi Hernandez. Mourinho addressed that moment in the documentary, stating that matches between Barcelona and Real Madrid were a war. Mourinho said players could exchange friendly greetings while on duty with the Spanish national team, but he refused to tolerate such gestures during club competition, adding that he would never accept a lack of respect.
National Team Conflicts
Casillas acknowledged the difficulty of that period in the documentary, explaining that acting as captain of both Real Madrid and the Spanish national team created a complicated conflict. He said he had to compete against opponents on the pitch who were simultaneously his international teammates. Casillas noted that he disliked the hostility between the rival clubs and raised his concerns directly with the manager.
Speaking on his podcast, Casillas confessed that he regretted not confronting Mourinho directly in his office at the time. The former goalkeeper emphasized that he attempted to limit the public conflict and avoid creating more of a circus than already existed.
Addressing the unresolved identity of the informant, Casillas remarked that the mole leaked the lineups and challenged critics to search for and find out who the mole was. Rui Faria, who served as Mourinho's assistant coach during that era, said the technical staff were almost certain of the informant's identity because team details consistently appeared in newspapers, although they could not legally prove it.
Brazilian defender Marcelo reflected on the lingering frustration among players from that squad, stating that team members still want to know the identity of the person who leaked internal details. Mourinho now returns for his second spell at Real Madrid under president Florentino Perez, who believes the Portuguese manager can restore order to a dressing room currently displaying signs of tension.
