The Spain international, 31, endured a difficult 2014-15 campaign in which he made just 19 starts in La Liga and some have questioned whether there is still room for him in Luis Enrique's style of play.
However, the attacking midfielder has insisted that he still has plenty to offer and is happy at Barcelona.
"It is not true that I am suffering in Luis Enrique's style of play," Iniesta told Mundo Deportivo.
"In the end, you always have to find your place and feel well in a certain formation and I am able to continue doing just that. Is is true that perhaps some things have changed for me, but that is not a negative thing in my opinion.
"I have gone through all kinds of moments last season, with different emotions, I don't think it was a bad season for me on a personal level. I am more than happy both on an individual and collective level for what we achieved.
"I am hoping for an even better season on both levels in 2015-16."
Iniesta has become one of Barcelona's more experienced players following the departures of Carles Puyol, Victor Valdes and Xavi in recent years and he is happy to take on any extra responsiblities as the club's new captain.
"I think it's nice that I am one of the older players. It means that I have been around for a while and I am still here. That has always been the objective. I am really happy.
"It is very special to represent the team as the first captain. It is very nice. It is amazing to become the captain for a player who has been at Barcelona for so long.
"I don't think there is just one way of being a good captain. I have been fortunate to have played alongside captains such as Puyol and Xavi. A captain thinks about the group before his individual interests. Being a captain is about so much more than just football."
