The curtain will come down on his career at the Camp Nou at the end of the campaign as he begins a new adventure in China.
As he prepares for that exit, Iniesta's career was discussed by Zidane, who waxed lyrical on the Spain international.
"It is difficult because if you like football, seeing a player like him leave is tough," the Frenchman told reporters.
"I don't think of him as a Barcelona player. I see him simply as a football player.
"I've come across him two or three times and he is a charming, very reserved man and I like players who can do everything on the field but are that calm off it.
"I only have good words for him, admiration for his football and I wish him the best as a player for the future but above all, as a person.
"We're talking about someone who made everyone dream and he deserved to win the Ballon d'Or, especially in the year he won the World Cup.
"It was clear then that he deserved it."
