Lazio forward Ciro Immobile put the hosts ahead in the 23rd minute against the run of play when he latched onto a weak clearance and swept the ball into the net after it took a slight deflection off a Czech defender.
Inter Milan midfielder Nicolo Barella doubled the lead for Italy just before the break when he dribbled toward goal and fired a shot home from just outside the penalty area.
Napoli midfielder Lorenzo Insigne marked his 30th birthday with a goal in the 66th minute when he took an Immobile pass and sent a sharp right-footed strike past the keeper.
Insigne turned provider minutes later when he set up Domenico Beradi, who made it 4-0.
