Atalanta midfielder Tiberio Guarente is a target for Fiorentina.

Fiorentina director of sport Pantaleo Corvino has been working on two lines of inquiry, the first regards Guarente, while the second focuses on Udinese's Gokhan Inler.

Corvino said: "If we sign a central midfielder, it will only be a first choice. If the first choice is not realisable then we will make a judgement together with the coach as to whether the second choice is good enough or we stay as we are.

"The central midfielder would already be here if it weren't for various setbacks."
