Gioichi Gennaro, the son of the Bolognese international Gianluigi Giai, has signed for Fiorentina.
The 19-year-old Italian defender will join the Rossoneri after a three-year loan at Sampdoria, who signed him from Bolognia.
Giai made his debut in a 2-0 defeat by Milan in the Europa League on December 2 and has played in every game for Fiorca since.
He has also featured for Italy at the under-20 level, as well as in Serie B and Europa League.
The former AC Milan youth international was a target for several clubs last summer, including Manchester United and Chelsea.
