Tottenham and Newcastle United are weighing up January approaches for Fabbrini.
The player's representative, Beppe Galli, told Sport Italia: "Fabbrini is a talent, but he needs to play to show that.
"It's certainly not an ideal situation and the player himself has asked for more space in the side to prove himself.
"To get value out of a youngster you have to give them a chance.
"I've spoken with the club and if things continue as they are then it would be right to find a solution that would allow him more regular playing time."
