The Welshman was expected to take on the leadership role in the absence of Ronaldo but has been criticized for so far failing to do so.
The man who was part of Portugal's victorious Euro 16 squad said that no amount of money could make up for the absence of the five-time Ballon d'Or victor, Ronaldo. He was always encouraging them to play better, to train more.
"It is hard to know [why he left], I do not know what happened, but I know how Cristiano is, he has an ambition the size of the world, he wants to always do things well and show that he is the best".
"Massimiliano Allegri is someone who I think listens to the peers that he has around him", he told BBC Radio 5 Live's Football Daily podcast. "Not for €200 million, no".
Juventus' current manager Massimiliano Allegri is reportedly on the Real Madrid's radar again after publicly revealing he turned down an offer to replace Zidane, who guided Bernabeu to three Champions League title, at the end of last season. He alleges that Zidane wanted to sell Gareth Bale and keep the Portugal star.
"Zidane also wanted to sign some players and transfer others-apart from Bale-but he didn't get [his wishes], so he chose to leave".
"He insisted on keeping Cristiano and transferring Bale, and the president did completely the opposite".
But in fact, Perez "did the opposite" to what Zidane had asked.
Real Madrid head into Sunday's match fifth in La Liga, outside the Champions League places and ten points behind league leaders Barcelona.
