Real Madrid conceded first before thumping Real Valladolid on Sunday.
Valladolid were unfortunate not to be well clear as Ruben Alcaraz missed a penalty and Sergi Guardiola had two goals ruled out before Anuar's opener.
Raphael Varane equalised from close range and Karim Benzema then scored twice, from a penalty and a header.
Casemiro was sent off for two yellows before Luka Modric added a fourth.
Third-placed Real, who have only won two of their past six games, are 12 points behind leaders and champions Barcelona.
