Italy showed why they are among the favourites for the Euro U21 title in outclassing the host nation, whose chances of a recovery were buried when Eyal Golsa was sent off for a clumsy two-footed tackle on Riccardo Saponara on 34 minutes.
Saponara drove a lovely finish into the corner of the net after Ciro Immobile had played a deft lay-off into his path from Lorenzo Insigne's cross for the opening goal on 18 minutes.
Gabbiadini hit the net from Immobile's pass on 40 minutes. It was a brilliant move and finish against the 10 men even if poor goalkeeping by Boris Klaiman did not exactly help the situation.
The second half was a non-event as Italy exploited the space against the 10 men with some relish.
Gabbiadini thumped a free-kick low past the wall to hand the Italians a 3-0 lead before Florenzi scored a fourth goal for Italy that saw him slip the ball through the legs of Ben Vahaba and then under Klaiman to finish off matters.
One point of concern for Italy was an injury to Insigne, who they will hope to have available for the semi-finals of the tournament.
Italy will progress to the last four as Group A winners if they avoid defeat against Norway in their final group match on Tuesday.
