Casemiro was at risk of being suspended for the Clasico on the original date and things have not changed. Casemiro was a booking away from suspension just before the Clasico in October. However, that did not take place and Casemiro could breath easily.
Just over a month and a half later, the situation is the same for the midfielder who has yet to pick up that fifth yellow card so he has yet to be suspended.
The match against Espanyol looked the perfect match to miss to prevent being suspended for the Clasico, but Casemiro failed to see yellow against Alaves.
Therefore, the Real Madrid player has only got one more chance to get a yellow card prior to the Clasico and that is versus Espanyol. However, if he did that, he would be forced to sit out the tough encounter away to Valencia.
The importance that Zidane has given Casemiro this season has been great. The Brazilian has started the 19 games for Real Madrid in La Liga and the Champions League this term. Not even the irruption of Valverde has managed to stop a player who is now a nailed on starter for Brazil. His possible absence in Barcelona is something which greatly concerns Real Madrid fans because of his importance.
