The Croatian midfielder also hailed Zidane's man management ability.
"Zidane once again proved to be a great person," he noted.
"He is reassuring and he is very correct in his approach to the player.
"There are always those who do not play as much as they would like, they are not happy and that makes sense.
"But the coach's approach has helped everyone feel part of the team and accept their situation.
"In this dressing room, everyone is a good guy, there is no one who creates problems for their own reasons, there are no bad apples."
