Madrid were not amused by the behaviour of Barcelona in last week's Champions League match and have demanded disciplinary action against six players
Barca recorded a 2-0 win over the capital club, but the match was marred by incidents as Jose Pinto, Pepe and Jose Mourinho were all dismissed during the contest.
Madrid have allegedly demanded two-match bans for Dani Alves, Sergio Busquets and Pedro for their unsporting behaviour, and have also asked Uefa to suspend Javier Mascherano, Seydou Keita and Victor Valdes for one game for their involvement in various altercations.
Uefa's disciplinary committee meets in Nyon on Monday to discuss Madrid's complaints and is expected to announce its decision before Tuesday's second-leg at Camp Nou.
Real Madrid have also asked Uefa to take action against head coach Pep Guardiola as they believe that the behaviour of Barca's players was part of the tactician's 'premeditated anti-sporting' plan to disrupt the Bernabeu giants.
