Vucinic is on-loan at Roma from Lecce.
He said: “I am pleased with my performances so far and I am finally getting back to my best shape.
“I like it here as this is the club I had been dreaming about for so long and I hope I will stay.
“It is now my objective to win a place in the first team. When you take into account my previous fitness struggles, I am sure I can do even better.”
