"I recharged my batteries and now I'm ready to lead, be the coach of Real Madrid and giving me the opportunity of being again with this great club," said Zidane during a press conference.
"My ambition and what I have inside me for this club, no one's going to take away the excitement of coaching again."
"I'm going to give it all - everything I have inside me so we are a team that does better," added Zizou.
In the previous season, Zidane led Madrid to a historic third consecutive Champions League triumph.
But narratives have changed at Madrid since his exit as the club is going through a crisis situation.
Real's former player Cristiano Ronaldo's departure in July to Juventus has had a big impact on the club this season while their other key players, like Marcelo, Isco and Gareth Bale, have struggled.
During the press conference, Zidane also said that finding Cristiano Ronaldo's replacement is not the first thing on his mind.
"He (Ronaldo) was part of this clubs history and no one's going to change that. He was the best or one of the best, and that's it. But that's not the point, to talk about these things now," said Zidane.
