Casemiro can't believe people are questioning Real Madrid coach Zinedine Zidane.
The midfielder also revealed that the Frenchman was his idol as a player and stressed that Zidane will be remembered as one of the finest coaches in the history of European football.
"It's very easy to talk about Zidane," Casemiro told UEFA's official media. "As a player, he was always my idol, because he played in midfield.
"His qualities are different to mine, but I appreciate his style. And as a coach we don't realise what Zidane has really done and what he is doing for the good of Real Madrid.
"Very few coaches have been able to achieve what he has so far, especially his achievements in the Champions League.
"His achievements as a player and as a coach will be remembered in 20 or 30 years because what he is doing now will stand the test of time.
"This will be brought up when the history of Real Madrid is spoken about."
