Fiorentina continue to be active on the transfer market and are looking to bring in a defensive reinforcement for Italiano's backline.
The Tuscan club have been in talks to bring back Matija Nastasic who played at the club between 2011 and 2013 before moving to Manchester City.
Although an agreement with Schalke has yet to be reached, the conversations between the parties are ongoing, Nastasic's future could be tied to Milenkovic's potential departure, following Schalke's relegation, Fiorentina could acquire Nastasic on a free transfer or by paying a nominal fee.
