The Brazilian starlet is relishing the prospect of linking up with the star trio as he prepares to complete his "dream" move to Camp Nou
The 21-year-old will join the Liga champions for €28 million after agreeing a five-year deal and he is desperate to play alongside his new team-mates after his final match for Santos on Sunday.
"To play with Messi, Xavi and Iniesta is a great honour," he told reporters after his side's game with Flamengo.
"It's a dream to be going to Barca. I leave Santos through the front door. I hope to return to my second home [in future], which is Santos.
"I feel fantastic, very happy and grateful to Santos and I'm already thinking about Barca."
The Catalans had been using Brazilian defender Dani Alves to lure Neymar to Camp Nou and the 21-year-old joked: "Alves was the one who insisted [I join Barca]."
Neymar was visibly emotional prior to kick-off ahead of Santos' clash with Flamengo on Sunday, but the game itself was a drab 0-0 draw.
