The RB suffered a knock in the derby, although he finished the match without any apparent problems. It isn't known if he has any physical injury, but it seems that he has is a slight niggle, as he wasn't at Monday's session.
If he can't play the next match, Zidane will have a problem. After Álvaro Odriozola moved to Bayern, Zidane doesn't have any other RBs. If he can't play, Nacho Fernández will play there, like he did against Valladolid.
Another player that didn't train was Mariano Díaz, who Zidane hardly uses and has only played 44 minutes this season for Real Madrid.
Marco Asensio continues with his recovery process from a left knee injury that he suffered in pre-season and worked alone with the ball.
After enjoying a day off after the derby win, the rest of the players completed the first preparatory session of the week that the coaching focussed on possession and pressing exercises and that ended, like normal, with a small-sided match, the club informed in a statement.
