Real beat Liverpool 3-1 in the final in Kiev on Saturday, making Zidane the first coach in history to win three successive Champions League titles.
Zidane's decision shocked much of the football world, with president Florentino Perez only informed yesterday, and Ronaldo was keen to thank his boss for their time together.
Zinedine Zidane'sdecision to quit Real Madrid came as a surprise to even his friends, former global teammate Christian Karembeu told ESPN FC and revealed he spoke to the departing head coach in the days before the announcement and had no idea of the decision. "First for me, the squad, the club I think it's a bit of a weird moment but an important one that is good for everyone", the Frenchman said.
"The team needs to continue winning and needs a change", said the outgoing manager. 'He gave me the opportunity to come as a player and now manager and I am eternally grateful. "After three Champions Leagues in a row, and titles he chose to leave". I would have liked to convince him to stay on but I know what he's like.
The former Arsenal manager has attracted the early backing, seeing his odds cut from 6/1 since confirmation of Zidane's departure.
"I don't want this to be a goodbye, just a "see you soon".
"All in all, he felt that the distance between players and manager, the authority of the manager, had been hurt". I am not exhausted of coaching, after three years.
There was also a lot of intrigue after Zidane said: "I think it's the moment, both for me, the team and the club (to step down). I thank him for the work he has done".
Zinedane Zidane has announced his resignation from Real Madrid today.
"He senses that the players need something new, they need a new voice".
Now the second favourite for the job is ex-Madrid star Guti, who has been coaching Real Madrid youth teams ince 2013.
