The Portuguese club alleges that Valverde punched or violently struck Dahl in the 82nd minute, an act they believe warrants a red card. The incident, which occurred near the sideline, was missed by the referee and not reviewed by VAR.
Despite the severity of the alleged misconduct, Valverde is expected to play in the second leg. The complaint adds further tension to the upcoming clash, following previous incidents involving racist abuse and heated post-match comments.
