The Giallorossi chief has ruled out the possibility of the striker leaving in the summer and noted that the club are very happy with his recent displays
The 20-year-old signed for Parma at the end of last season but moved to Roma in August on a co-ownership deal.
Borini has been a big hit for the Giallorossi, with seven Serie A goals to date, which earned him his maiden call-up to Italy's senior team.
"Borini left his mark against the United States, he is pure power," Sabatini told Sky Sport Italia.
"He does it every day in training and at weekends during matches. We are happy with his performances.
"[Roma coach] Luis Enrique has done a great job with him, turning a prospect into a certainty.
"He will surely stay at Roma. We have an agreement with [Parma CEO] Pietro Leonardi that the deal will be renewed in June and we will then discuss the following season."
