The Barcelona chief is confident the Spain international will end his career at Camp Nou and added that he is a fan of goalkeeper Thibaut Courtois.
The Spain international has been holding contract extension talks in recent weeks but is yet to reach an agreement with the Spanish power where he has spent the duration of his career. But Rosell appears unperturbed by the delay, hinting that a new deal will eventually be signed.
"Iniesta will end his career at the club," Rosell told Cadena SER. "If I had to bet on his future, I would do so on that. We believe he should be the second-highest salary behind Messi."
Barca is still on the hunt for a new goalkeeper, with current No. 1 Victor Valdes set to run out his contract next summer, and rumors that a move for Thibaut Courtois could be in the pipeline have been fueled by the president's praise of the Chelsea shot-stopper, who is spending his third season on loan at Atletico Madrid.
"Courtois is a keeper that I really like - he is very good," Rosell said.
Barcelona has made a perfect start to the new Liga season, winning all eight of its matches to date, and the club resumes its campaign with a trip to Osasuna on Oct. 19.
