NORWICH CITY's Development Squad were in clinical form as they dispatched Crystal Palace 5-1 at the KNK Stadium on Monday night.
First-half goals from Josh Murphy and George Francomb had given Scott Marshall's side a cushion at the break, before Jamar Loza and Jacob Murphy netted within a couple of minutes of each other to put the Barclays Under-21 Premier League encounter beyond doubt.
Korey Smith fired home City's fifth five minutes before the end, although Palace did secure a consolation goal when Kwesi Appiah slotted home a penalty moments later.
The win was the Canaries' third of the phase and will have impressed watching first-team manager Chris Hughton.
Coach Marshall told canaries.co.uk after: "It was a really good performance, I'm delighted.
"The boys showed a really good attitude - the conditions weren't fantastic but the boys were really up for it. They showed some quality as well and got the five goals that they deserved.
"We counter-attacked very well, all the goals were decent goals and it's always pleasing when we get a few guys on the score-sheet as well."
City looked bright from the off as Jacob Murphy, playing in a central position just off of main forward Loza, stung the hands of David Gregory, although Sullay Kaikai did the same to Remi Matthews with a free-kick up the other end.
The visitors were the side on the offensive, though, and after Gregory denied first Francomb and then Loza, Josh Murphy gave them a merited lead when he finished from six yards after a mix-up among the Palace defenders.
After Matthews made an expert stop to deny Appiah on 35 minutes, Norwich raced up the other end and doubled their lead - Loza's precise pass found the on-running Francomb, who finished calmly and set the Canaries well on their way.
HALF-TIME: Crystal Palace 0-2 Norwich City
The second-half got off on a more even keel, but Norwich punished the home team for some more error-strewn defending on the hour when Loza grabbed a goal to add to the two he scored in last Wednesday's Norfolk Senior Cup win at Cromer Town.
Three became four a couple of minutes later when Jacob Murphy curled a fine shot in from the edge of the area, and at this stage City looked rampant.
Palace managed to steady the ship, though, and it took until 85 minutes for City to grab a fifth through senior professional Korey Smith's drilled shot.
The small home crowd who braved the conditions got a reward a minute later when a handball in the City box saw the referee point to the penalty spot.
The dangerous Appiah stepped up and sent Matthews the wrong way, but it was City's night as they saw it through to end for a superb win.
