Newly-promoted Crotone are very active on the market, close to Crvena Zvezda midfielder Milos Vulic, Andrea Rispoli, Luca Cigarini and Emmanuel Riviere.
The club from Calabria earned promotion by finishing second in Serie B last season, behind Benevento.
According to Sky Sport Italia, they are stepping up the reinforcement process rapidly, clinching 24-year-old Crvena Zvezda midfielder Vulic on a three-year contract, pending a medical.
They have also done a deal for Lecce right-back Rispoli, who turns 32 later this month.
Sportitalia point towards a couple of free agents that Crotone are also picking up.
They are veteran ex-Cagliari midfielder Cigarini and 30-year-old former Cosenza centre-forward Riviere, who scored 13 goals in 31 Serie B games last season.
