Real Madrid coach Zinedine Zidane says they have much to improve after their 3-1 defeat of Eibar.

Los Blancos scored all three of their goals in the opening 45 minutes before allowing their visitors back into the game after half time.

"I don't know, it's something completely different, but we have to adapt," Zidane said on the new conditions for football.

"We found it difficult in the second half.

"I don't know if it was the physical side, but we weren't on it.

"The first half was good and convincing.

"It's three important points.

"There are 10 games left."

Zidane had made four of his five available substitutes after just 61 minutes, with some suggesting that affected their performance.

"Maybe, because everything about the first half was good and it was 3-0, so maybe we relaxed," he said, after seeing Toni Kroos, Sergio Ramos and Marcelo score for the hosts.

"I had to make the changes.

"The first change was because Carva [Dani Carvajal] twisted his ankle, [Sergio] Ramos had annoyances and Eden [Hazard] hadn't played for a while.

"But I don't think it was the substitutes that changed the game."
