The Liverpool striker was the subject of no fewer than three bids from Barca during the off-season as the Reds refused to part ways with their star player.
However, the Catalan giants are expected to again return with an offer for Coutinho, who himself is believed to be keen on a move to the Nou Camp.
And Barca legend Iniesta is keen to see the Brazil international plying his trade in La Liga, telling Football Espana: “Coutinho is a great team player with lots and lots of talent, he would be fantastic for us.
“He is equally adept with both feet, he links up well with other players, scores goal and gets between different phases and lines in attack, he would be what we want.
“His qualities fit into how we play and what we want and if the signing is finally complete, it would be great.”
