The Italy midfielder is frustrated by the lack of regular action he's seen so far this season.
La Gazzetta dello Sport says Frattesi will try to secure a move away from Inter in January.
The midfielder has made seven appearances in Serie A this season, but only one match from the start.
Atletico Madrid, Napoli, Roma and Juventus showed interest in the midfielder this summer.
With Newcastle also keen, Inter are not open to selling the player to a direct Serie A rival.
