Castilla coach Santiago Solari steps in to take charge of Real Madrid after the dismissal of Julen Lopetegui.
The 5-1 defeat at the Camp Nou against Barcelona was the final straw for president Florentino Perez.
Solari moves up from the Castilla side, as did Zinedine Zidane did three years ago when replacing Rafa Benitez.
It is a decision that has been taken to pull the club out of a crisis that has rarely been experienced at the Estadio Santiago Bernabeu.
Solari's career in the dugout has been developed at La Fabrica.
He debuted with Cadet B in 2013 and was promoted to the A side a year later and Juvenil B in 2015.
In 2016, he took over as Castilla coach and is now the latest emergency solution who Perez has found at home.
