“In 2018 my contract ends and my desire is to continue, the whole world knows this, it is no secret. But my level of performance will determine if I can stay at Barça. I hope it will be for a long time,” the 32-year-old said in an interview with sports daily Mundo Deportivo.
Barcelona recently reached a deal to extend the contract of Uruguay striker Luis Suarez to June 2021. His previous deal was due to expire in 2019.
In October, the club also extended the contract of Brazilian superstar Neymar until 2021 and they have already started talks to seal a new deal with Lionel Messi.
Along with Messi, Iniesta is Barcelona's most decorated player ever with 29 trophies, but he is even more loved across Spain for his winning goal in the 2010 World Cup final against the Netherlands.
Iniesta is second behind only former teammate Xavi Hernandez as the player to have made most Barca appearances.
He is also hopeful coach Luis Enrique will renew his contract with Barcelona when his current deal expires at he end of the season.
“He is very motivated, I hope we can remain together and keep celebrating things, which is what we all want,” Iniesta said.
Barça have also already tied down Sergio Busquets and Javier Mascherano to contract extentions this year.
