Real Madrid coach Jose Mourinho has been charged by UEFA after they launched an investigation into whether Sergio Ramos and Xabi Alonso deliberately incurred red cards during Tuesday's Champions League match with Ajax.
Ramos and Alonso, together with Jerzy Dudek and Iker Casillas, are also under investigation for alleged improper conduct.
A statement from UEFA said: "UEFA has confirmed that a disciplinary case has been opened against Real Madrid for the improper conduct of coach Jose Mourinho and players Xabi Alonso, Sergio Ramos, Iker Casillas and Jerzy Dudek during the UEFA Champions League Group G match against AFC Ajax in Amsterdam on Tuesday."
The case will be dealt with by the UEFA Control and Disciplinary Body on Tuesday, November 30.
Alonso and Ramos were both sent off late in the 4-0 win in Holland after receiving second yellow cards for time-wasting.
That means the two Spain internationals will be suspended for Madrid's final Group G match against Auxerre - which is a dead rubber for the already-qualified Spanish side - but could see their disciplinary records wiped clean ahead of the knockout stages.
