The Frenchman has long been linked with a move away from Turin, with both the Catalan giants and Real Madrid said to be very interested in him.
Pogba has now spoken of his admiration for Barca - his side's Champions League final opponents on Saturday - singling their Argentine star out for particular praise.
"Playing with Messi would be a dream come true," he is quoted as saying by AS.
"He's the best player in the world. I love watching Barcelona play, but I also love watching them lose. We know that we're not favourites but it's a final.
"We're going to give our all. We have nothing to lose and you never know what can happen."
Despite his admiration for Barcelona, Pogba emphasised that he had no immediate plans to leave the club in the summer.
"I never said that the final in Berlin would be my last game. People can believe what they want."
Barcelona and Juventus kick off in the German capital at 20:45CET on Saturday.
