The Giallorossi are have suffered record losses and there have been fears they may have to cash in on Zaniolo.
However, chief executive Guido Fienga has told Morgan De Sanctis and Franco Baldini to find alternative income.
Zaniolo, 21, is one player Roma are determined to keep in a market where they could lose big names.
Italy midfielder Lorenzo Pellegrini is another the capital club are desperate to keep.
The squad has many players who are surplus to requirements and an effort will be made to sell them.
13 expendable players
Other players who could go include Alessandro Florenzi, Javier Pastore, Diego Perotti, Juan Jesus, Rick Karsdorp and Robin Olsen.
Before resorting to selling Zaniolo or Pellegrini, Roma will also listen to offers for players they would prefer to keep.
Amadou Diawara, Pau Lopez, Jordan Veretout, Gianluca Mancini, Cengiz Under and Justin Kluivert are important players, but ones who could be sold if necessary.
Zaniolo is the crown jewel of Roma and is valued between €60m and €70m, with Juventus known admirers.
But the club will do whatever it takes to hold on to him as they battle through a financial crisis.
And Zaniolo himself would be happy to stay with Roma, the club that launched his career after he arrived from Inter.
