The France international has been linked with a move away from Old Trafford but Raiola said he will not leave the club this summer.
"He is at the heart of the important project," he told Sky Sports Italia. "Even in previous years, United have never entertained offers."
Asked whether he is close a new contract, he added: "We are talking very calmly without any stress."
Last month, Pogba said he was "happy" at the club amid reports he wanted to join Real Madrid or Juventus.
United boss Ole Gunnar Solskjaer also said he was confident that Pogba would sign a new deal.
The midfielder performed well alongside Bruno Fernandes after the Premier League restart and helped United achieve a top-three finish for only the second time since Sir Alex Ferguson's departure in 2013.
Meanwhile, Raiola also cast doubt on Zlatan Ibrahimovic's future at AC Milan.
The striker's contract expired at the end of the campaign but Raiola is hopeful there is time to reach an agreement to keep the player at the San Siro.
"I don't believe he [Ibrahimovic] will join the Milan training camp tomorrow," he added. "While we are negotiating, we are at a good stage. We are talking, but not agreement as yet.
"It's not a money issue, but about conviction and style. A marriage is made successful with two people. If Ibra didn't want to stay, we wouldn't be negotiating, but we are."
