"I've taken the decision to not continue next year as Real Madrid coach", Zidane said.
On Zidane's decision to leave the LaLiga giants, Calderon said: "I think he's shown to be wiser than we thought". 'He gave me the opportunity to come as a player and now manager and I am eternally grateful.
"Zidane probably feels that if the players do not want to talk to me, they are not listening to me, I am not the one to take all that on board and change the dynamics".
Although Real lost only two of their first 15 league matches in the recently concluded Spanish championship, Ernesto Valverde's Barca were able to run away with the league following their vital 3-0 El Clasico win at the Bernabeu in December. It has been impossible to convince him.
The former Arsenal manager has attracted the early backing, seeing his odds cut from 6/1 since confirmation of Zidane's departure.
But he also added: "I'm not exhausted of coaching after just three years of coaching".
'I love this club, I love the president, ' he said.
"Perez may now appoint Guti: it would be his own decision, he wants to show he can do radical choices as he did three years ago with Zidane".
"If I was the manager here next season, it would have been tough for us to win trophies".
The 45-year-old Frenchman played 155 times for Real Madrid and became a club legend, before taking over the B team, Castilla.
"I have a special love for this fanbase".
Zidane, under contract until 2020, gave no explicit reason for stepping down, but said he is not now seeking to coach another team.
