Barca felt that these allusions to the Negrera case, which is still pending in court, went beyond the bounds of normal sporting competition.
The provocations came after statements and reactions on and off the field, with English player Jude Bellingham saying to the referee during the match: "Not even with Negreira!" after a foul he committed on a Barcelona player, which Barca considered a direct provocation of a legal issue.
For its part, Barcelona's management denounced what it considered a "clear double standard," since while the Negreira case is being investigated, Real Madrid is allowed to allude to it almost publicly in sporting events without reservation.
Catalan newspapers indicate that this media control, psychological harassment, and provocative practices towards Barcelona's young player Lamine Jamal are part of a "witch hunt" that the club feels.
On the refereeing side, the crisis comes amid accusations and a lack of confidence among Barca fans regarding the performance of referees during matches against Real Madrid, as the club believes that repeated refereeing errors are burdening it, while opposing players are not questioned about their hints or behavior.
Jamal sparked widespread controversy in recent days after accusing arch-rivals Real Madrid of "stealing and complaining," which ignited a wave of anger in Spanish media circles.
During the last Clásico, the 18-year-old was involved in several altercations with Real Madrid players.
