The Camp Nou outfit had a 2014-15 to remember, with the Catalan giants winning a momentous treble do dominate Spain and Europe.
After an off-season break, Luis Enrique’s men will return to competitive action tonight as they take on Sevilla in the Uefa Super Cup.
Iniesta, who has been handed the Barca armband since the departure of Xavi to Al Sadd, has been singing the praises of long-term team-mate Messi.
The Argentine was irrepressible in Barcelona colours last season and is currently the red-hot favourite to win back his Ballon d’Or crown at the end of the year to make it an unparalleled fifth personal success.
With Messi set to feature against Sevilla, Iniesta has lauded the versatile forward.
"Having Messi in your side, the triumphs just keep on coming,” Iniesta is quoted as saying by Marca.
“That’s not only the case right now. We've been enjoying his football for quite some time now.
“We look forward to seeing him shine once again this season and we hope to be able to see him strutting his stuff in the UEFA Super Cup.”
Barcelona and Sevilla clash in Tblisi, with the Camp Nou side on track to win an incredible six trophies over the course of the calendar year.
Messi will be keen to put summer disappointment behind him after he skippered Argentina to a finals defeat in the Copa America against Chile.
