Enzo Zidane says his father "listened to his heart" in making the decision to return as Real Madrid head coach for a second stint.
He was replaced by Julen Lopetegui, who lasted mere months before being sacked in favour of Santiago Solari.
That paved the way for Zidane's remarkable return, much to the pleasure of the manager's son.
"I'm happy, like any son with his father," Enzo Zidane told Sport.
"I hope he comes out the best he can, I trust in his work and I support him as always."
He added: "[He] always makes decisions with his heart and it worked out like that. When you do things with your heart they go well and I'm sure it will be great.
"If Real Madrid are now in good hands, I do not have the answer to that. It's the people who speak, I'm happy as a son and as a Madrid fan."
Enzo was with Real Madrid for over a decade, having joined as a youth player in 2004.
In July, Enzo returned to Spain, joining Rayo Majadahonda in the second division on a one-year loan deal.
Rayo Majadahonda cruised past Numancia with a 4-0 win in their most recent match, and Enzo says the team is beginning to feel more comfortable.
"At last we play a game in which we are calm at the end, a game with an advantage," he said.
"The first part has been very good, the whole team entered tense, very well and getting goals.
"We have played several very good matches, what we always want to do better and we will keep trying every weekend with the best goal to get the maximum points this season."
