Zidane said there wasn't a specific reason that led him to his decision, but apparently he saw enough signs to know things were not all perfect despite the good results.

"After three years, (the club) needs a change in speech, a new work methodology," he said.

Zidane mentioned the struggles the team faced this season, including in the Spanish league and the Copa del Rey. Madrid finished third in the league — 17 points behind champion Barcelona — and was eliminated at home by Leganes in the quarterfinals of the Copa del Rey, a moment which Zidane said was the worst of his coaching career with the club.

"We went through good moments but also complicated ones, and I don't forget them," Zidane said. "I want to leave when everything is going well. This is a good moment to end it well."Zidane said his best moment with Madrid was when he was signed to play for the club in 2001. He won the Champions League with the club in 2002, scoring an amazing volley in the final against Bayer Leverkusen.
