The Spain international has revealed his continuing admiration for the 34-year-old, whom he played alongside during the early part of his career at Camp Nou
The pair were at Camp Nou during Louis van Gaal's time in charge of the club, and although they only played together for one year, the Argentine left a lasting impession on the Spain international.
"It is always sad when a world-class player such as Riquelme is no longer in the pitch. If he decides to retire, football has lost one of the best," he told Augol.
"I was lucky to have met him in my early years at Barcelona. After so many games, after so many good times we enjoyed and we've seen, I can say that I am delighted to have been his team-mate.
"When I played with him and when I've seen him play what I liked most was the class that he had with the ball, the passes he made, the combinations.
"He is a player with whom I identify, in the sense that he gives the football and asks for the ball at all times."
Iniesta went on to admit that he remains in awe of the way current Barca colleauge Lionel Messi makes things so look so effortless on such a regular basis.
"With Leo I do not see any flaw. It is impossible to have a defect when you're number one, with each match he can decide what and when he makes the hardest things seem easy.
"I have spent many years sharing a dressing room with him and train every day. He is very young still, bearing in mind what has been achieved and what remains to be achieved.
"Year after year he exceeds himself. He is unique."
When asked whether he would consider plying his trade in South America, Iniesta insisted that he was focused on matters at Camp Nou, and refused to speculate on a coaching career in the future.
"My dream is to finish my career at Barcelona. I arrived here at a very young age, and it would be nice to finish my career where I started.
"From what I hear from colleagues and from what I have seen of the Argentine championship it would be very nice to play there, for the environment, for the opponents.
"Today I do have not in my mind that I will be a coach. I'm sure I will continue to be linked with football, because this is my life and without it I do not really know what I would do.
"But I do not envisage the idea of management at the moment."
