Real Madrid pair Sergio Ramos and Cristiano Ronaldo could reportedly be punished for their comments following Los Blancos' 4-3 defeat to Barcelona in El Clasico.
Ramos, who was sent off in the second period, criticised Alberto Undiano for his performance at the Bernabeu, thoughts that were echoed by Ronaldo.
According to reports in Spain, the Referee's Technical Committee will review the comments made by both individuals, which could see the pair receive fines and possible suspensions.
Lionel Messi scored a hat-trick in the Spanish capital as Barcelona moved just one point behind Madrid, who sit second in La Liga due to Atletico Madrid's superior head-to-head record.
