Real were able to defeat Levante 3-2.
“All I can say is, I hope he keeps this up," Zidane said of Benzema.
"It's important for us to have Karim playing like this. We're pleased, we noticed the fans' ovation. We need to carry on like this and try and improve on the second half. I've been hearing how Karim's last game was his best for a very long time."
He added: "We know that we can produce much better performances and we'll go about doing that in a relaxed way. We have to play better and perform for longer spells in the game. That's what you'll see us do."
