A pair of goals from captain Thiago, along with lone strikes from Isco and Koke crowned la Rojita junior champions of Europe, despite Ciro Immobile and Fabio Borini's attempts to cause an upset in Jerusalem, but the scoreline heavily favoured the Italians who were dealt a harsh lesson in the basics of possession play.
The Spaniards showed their intent earliest and it was aptly rewarded when a fine interchange between Isco and Alvaro Morata down the left flank resulted in the Real Madrid striker crossing the ball onto the head of an unmarked Thiago in the box.
But moments later, just when it appeared that Italy were reeling from falling behind so prematurely in Jerusalem, a raking pass dropped at the feet of Immobile who delightfully lifted the ball over a hapless David de Gea on the half-volley.
It was game on between the giants of the U21 game, yet it was the Spaniards led by Morata - top scorer in the tournament with four goals prior to kick-off - who were more likely to find the back of the net again.
Morata first saw a powerful header denied by the fingertips of Francesco Bardi, before latching onto Thiago's through-ball a split-second later and firing again at the Brescia goalkeeper.
Nonetheless, he was to be the recipient of the honour.The onus switched away from the Castilla hit-man as the first half gradually came to a close, and Koke was the next to test Bardi via Isco's free kick.
The Malaga star's free kick rebounded to the midfielder, but his flick was stopped by Bardi's leg. The end-to-end nature of the opening spells soon returned, and it was Alessandro Florenzi who lifted the ball over his marker and hit a volley that took several bounces before being parried away by De Gea.
But on the half-hour mark, Spain deservedly regained their lead when Koke sent in a lobbed pinpoint pass onto the chest of Thiago, and the Barcelona starlet evaded Luca Caldirola before creeping a low shot over the line.
Eight minutes later, Cristian Tello peeled inside from the left flank but was brought down by Giulio Donati in the box, allowing Thiago the chance to grab his second from the penalty spot through the middle of Bardi's goal.
The second half started with a pair of snapshots from Isco and Florenzi to get the juices flowing, but Spain were undeniably on top as they continued to claim the lion's share of possession and dazzle purists with their intricate passing game.
Spain then found a deserving fourth - again from 12 yards out - when Martin Montoya's legs were clipped by Vasco Regini, and it was wantaway No.10 Isco who was entrusted with the burden of sending Bardi the wrong way.
However, Italy did show signs of an improvement with time fast becoming a precious commodity, and they managed to salvage some pride with just 10 minutes remaining as Borini scored in his second consecutive match following an intelligent one-two with Lorenzo Insigne.
