Reports in the Italian media claim the Viola are considering strengthening their squad by signing the Liverpool midfielder.
However, Aquilani's agent, Franco Zavaglia, told Tuttomercatoweb.it: "His future for the time being is at Liverpool. The player will remain there.
"With Fiorentina there are no negotiations in place, I have not even been approached by them. They are just rumours."
Aquilani, who spent last season on loan at Juventus, wanted to remain in Italy but received no suitable offers despite making 33 league appearances for the Turin outfit.
The 26-year-old was a reported target of AC Milan and Napoli this summer but announced earlier this month he will play in Anfield next season.
Liverpool signed Aquilani from Roma in 2009 and he is under contract with the Reds until June 2014.
