Ronaldo has scored in his last seven appearances in all competitions, and Zidane said: "He is from another galaxy". His stats speak for themselves.
Sergio Ramos thundered a shot wide after good defending from Ramis, while Ronaldo was denied his second goal by a fantastic save from Dmitrovic and Modric fired straight at the Serbian as Los Blancos improved just before the break.
"It's true that after 15, nearly 20 days, Luka came in and played a great game", Zidane said.
"He is a very important player for us".
Los Blancos struggled to get going in the first and they were dealt a blow on 28 minutes when Raphael Varane sustained a head injury.
The hosts were in a confident mood as they pegged their opponents back in their own half early on, with Kike twice close to connecting to threatening crosses from Takashi Inui.More news: Goldman Sachs CEO Lloyd Blankfein could leave at year-end
Eibar started the second half with confidence, and after a fierce cross from Gonzalo Escalante forced a diving save from Navas, the home side was soon level. The Welshmen though glanced his header from the resultant corner just wide of the target.
Isco and Kroos made way for Karim Benzema and Lucas Vazquez with 19 minutes left but Eibar had two golden chances to score a second.
But a defensive error allowed Dani Carvajal to cross and Ronaldo headed in.
Later on Saturday, Valencia moved back to within a point of Real and all but ended Sevilla´s hopes of finishing in the top four by beating Los Rojiblancos 2-0.
