The Bianconeri official is confident that the young Frenchman will add years to his existing deal in Turin, with a salary increase included.
The France international has emerged as one of Europe's brightest young prospects, with Bianconeri president Andrea Agnelli fueling speculation of a possible departure by claiming the club would accept a big-money offer for the 20-year-old.
However, Marotta insists that Pogba - whose current deal expires in 2016 - has no intention of leaving the Turin club, where he looks set to be offered the opportunity to extend his stay with the Scudetto holder for the near future.
Speaking to Sky Sport Italia, he said: "Pogba is happy at Juventus and he has no intention of leaving.
"We will meet with the Frenchman's agents soon to extend our agreement and, at the same time, we will give him a pay-rise for his development."
Marotta went on to comment on FIFA's short list for the Ballon d'Or and World Coach of the Year, with Juventus midfielder Andrea Pirlo and coach Antonio Conte among the nominations - the former of which is Serie A's solitary representative.
"We are proud," he added. "We re-launched Pirlo's career and that fills us with joy.
"As for Antonio, he is a young coach, an emerging one and the fact he is included is a motive of honour for all of us. The omission of Arturo Vidal? The only player nomination from Serie A is our playmaker, so this shows the selection was very rigid."
Juventus, which sits two points adrift of high-flying Roma at the summit of Italy's top flight, travels to Parma on Saturday, before hosting Real Madrid in Turin three days later in a crucial Champions League encounter with the Spanish giant.
