Alberto Aquilani hasn’t agreed a Fiorentina renewal, but is of interest to Atletico Madrid and Milan.
The former Roma, Liverpool and Juventus midfielder joined the Viola in August 2012, but his contract is due to expire in June 2015.
Aquilani, who turned 30 on Monday, has found contract extension negotiations hit numerous problems.
According to Sport Mediaset, Fiorentina have received an approach from Atletico Madrid for their Italy international.
Another option would be a return to Milan, as new Coach Pippo Inzaghi is said to admire his talents.
The Roman wore the Rossoneri jersey in 2011-12 while on loan from Liverpool.
