Vinicius Junior and Rodrygo stole the show with their goals and Zidane praised the Brazilian pair.
"I"m happy for them," he explained.
"Sometimes we forget that they're both teenagers and we saw the emotion of scoring at the [Estadio Santiago] Bernabeu.
"I liked Rodrygo's control, and scoring here for Vinicius was very important so he's very happy."
Madrid were tight and compact defensively, finally keeping a clean sheet, which pleased the coach.
"It's what we've been looking for," Zidane admitted.
"I think we're better and we'll try to continue this way.
"When we don't have the ball, everyone is worried about recovering it and then with the ball we know the quality we have."
