Fiorentina could exchange forward Mounir El Hamdaoui for Twente defender Roberto Rosales, while talks continue for Mario Gomez.
The Viola have been very active on the transfer market this summer and reports in the Dutch media claim an exchange is in the works.
Striker El Hamdaoui arrived from Ajax last season, but managed only three goals in 19 Serie A appearances, almost all of them as a substitute.
According to ElfVoetbal, Fiorentina have offered El Hamdaoui in exchange for Twente defender Rosales.
The 24-year-old Venezuelan right-back is out of contract in June 2014, so would be available for a cut price fee.
Meanwhile, reports continue in Italy and Germany that Bayern Munich forward Gomez is in advanced negotiations with Fiorentina.
