The Serie A champions have admitted for the first time that the midfielder could be sold if a big-money bid is made
The 21-year-old recently signed a new deal until the summer of 2019, but the likes of Real Madrid, Chelsea and Paris Saint-Germain are reportedly keeping a close eye on his situation in Turin.
Marotta has stressed Juventus will do all they can to ensure the France international stays put for as long as possible, but is realistic over the potential salary the midfielder could command elsewhere.
"We will do everything within out limits to hold on to Pogba, but we must not forget Italy is a country in transition," Marotta told reporters.
"The problem we have is that of offers coming in from other clubs offering him a salary that we are not able to match due to our financial situation.
"At the moment, there's no reason to believe that Pogba will definitely leave Juventus for another team, but we have to bear in mind that we cannot compete with the wages that are being paid elsewhere. We have our limits."
Pogba has been a key figure for Juventus this term, scoring seven goals in 24 appearances in all competitions.
