Fiorentina are already planning for next season and have earmarked Hamburg midfielder Piotr Trochowski as a potential transfer target.
La Gazzetta dello Sport understands the 27-year-old is Fiorentina's No 1 priority this summer, but they face competition from Sporting Lisbon.
Trochowski is out of contract in the summer and would represent a low cost addition to Fiorentina's midfield.
Meanwhile, it is also being reported that Fiorentina have bid €4.5m for Genk's 21-year-old striker Jelle Vossen.
Genk are apparently holding out for €5.5m and Udinese are also interested.
