Reports emanating from Italy have claimed the Serie A club are lining up a summer move for the former Roma forward.
Borini, who only joined Liverpool last summer, has endured a frustrating first season at Anfield with a series of injuries restricting his first-team chances, with a shoulder problem set to keep him out for the closing weeks.
The forward's agent, Marco de Marchi, insists he has not had any contact with Fiorentina and that Borini remains committed to Liverpool.
"I've heard the Fiorentina rumours, but there has been no direct contact," said De Marchi.
"Fiorentina are a club on the launch pad, they have laid the groundwork for an important project by signing great players and results will soon arrive.
"However, Borini has bought into the Liverpool project and they are one of the most important clubs in the world.
"He wants to be back by the end of the season to play in the European Under 21 Championship with Italy."
