Real Madrid coach Zinedine Zidane was left unhappy with fans after victory over Real Sociedad.
Karim Benzema once again failed to find the net, despite Los Blancos' free-flowing performance in the final third, which prompted yet more derisory whistles from sections of the home crowd.
However, the striker retains the support of his coach.
"I don't know why people do this," Zidane wondered.
"Obviously people can do what they want and he has had chances, but the important thing for him is to focus on the next game.
"This poor streak will end."
