Iniesta suffered a thigh injury on Sunday causing doubts regarding his fitness for the European decider to grow but he believes he will be available.
"I have already told the doctors that whatever happens, I am going to Rome," Iniesta told Spanish reporters.
"It is a slight blow and I am only thinking of Rome, where I will be.
"Unfortunately it happened during the last play of the game [...] and even if it is not that serious, I wish it never occurred.
"I am part of the best club in the world, people respect me and like me. We are a step away from winning the league and are due to play the Copa del Rey and the Champions League final.
"People's affection and respect is unbelievable and that is why I hope we will win these titles in order to make millions of fans happy."
