Iniesta signed a new deal that will keep him at the Spanish champions until 2014 on Friday.
“It’s a very special day,” he enthused to Barca TV.
“I want to thank the president [Joan Laporta], the board and [technical secretary] Txiki Begiristain for continuing to have faith in me. It’s one more step towards realising my dream, which is to retire here.
“I would like to end my career here, and look back and see all the titles that we have won – that’s what makes us happy. I will fight for this.”
