Frosinone are busy on the market after their promotion, close to Federico Barba, Lorenzo Crisetig, Marco Sportiello, Rai Vloet and Jacopo Sala.
The Canarini secured promotion thanks to a very controversial and ill-tempered Serie B play-off final against Palermo.
Now that they are certain of making the step up along with Empoli and Parma, they are active to reinforce the squad.
Multiple sources state they have a deal for Atalanta goalkeeper Marco Sportiello, who spent last season on loan at Fiorentina.
It would again be a loan move with option to buy for the shot-stopper.
Frosinone are also on the verge of securing Bologna midfielder Crisetig.
Other targets include NAC Breda creative midfielder Vloet and Sampdoria defender Sala, according to Sky Sport Italia.
Meanwhile, Sportitalia point to Sporting Gijon defender Barba – formerly of Roma, Empoli and VfB Stuttgart – and Perugia striker Samuel Di Carmine.
