Chievo Verona face a battle to hang onto young defender Andrea Mantovani.

Atalanta are already in advanced talks with Mantovani's representatives about a return to Serie A this season, however it's emerged that the youngster is also in the sights of Fiorentina sports chief Pantaleo Corvino.

Corvino sees Mantovani as an ideal understudy for prime right-back Federico Balzaretti.
