Le 10 Sport carries quotes from an Iniesta interview with Movistar during which the United and City transfer target reiterated his commitment to the Nou Camp giants.
The Spain international was briefly linked with a move away from Barcelona following a reported impasse in contract talks between club and player over an extension.
Barca reportedly offered him a £200,000-a-week deal - double his present salary - earlier this season but the Spaniard refused. But Iniesta has since denied the reports that he's holding out for a mega-pay rise, and the club have always been confident he would sign an extension.
City and United, as well as Paris St Germain, were thought to be monitoring developments, but Iniesta has closed the door on a potential switch.
"My future?" Iniesta told Movistar. "It's where we want [to be]. And me, my place is at Barca. The club knows this and wants us to continue together.
"I hope to be at the club as long as I want."
United and City were linked with Iniesta after reports emerged suggesting talks regarding an extension were faltering. His present deal expires at the end of next season, and he's yet to renew.
But Iniesta - who's spent his entire career at the club - clearly has no intention of leaving the Catalan giants anytime soon.
