Even though embarking on their maiden European campaign, Oliver Glasner's side are adapting at a rapid pace. Without key figures like striker Jean-Philippe Mateta and defender Daniel Muñoz, the London club departed Dublin with a commanding result that all but secures them a spot in the Europa Conference League qualifying rounds.
Another victory in their next fixture against Finnish KuPS ought to be enough to secure straight entry to the last 16, especially following a prior setback against Strasbourg.
This occasion provided a platform for some of Palace's lesser-used talent to shine. Christantus Uche, in only his second beginning since joining on loan from Getafe, opened the account with a clinical goal. Striker Eddie Nketiah contributed a another, scoring for the second game in match.
The Shelbourne team that had finished their league season were no match against a largely rotated Palace lineup. The visitors were already depleted by the reports that Mateta and Muñoz are out with leg injuries.
Despite torrential rain in Dublin, Palace quickly took control. A slick move in the 11th minute, sparked by Daichi Kamada's incisive pass, allowed Nketiah to lay on Uche for a straightforward tap-in.
Midfielder Adam Wharton came close soon after, fizzing a powerful shot over the bar. Nketiah then appealed for a penalty after bursting into the area, but the official dismissed the appeals.
The formerArsenal man did not have wait long to get his goal, tapping home from close range after Uche's effort had struck the post.
The home side were hanging on for dear life. Defender Kameron Ledwidge was fortunate to avoid a booking for a couple of robust tackles on Yeremy Pino, before Chris Richards rattled the woodwork with a powerful header from a corner.
The match was as good as over eight minutes from half-time. Yeremy Pino weaved past a series of weak challenges before calmly slotting a shot past keeper Wessel Speel to make it 3-0.
After the break, manager Oliver Glasner took the chance to withdraw key individuals like Kamada and Wharton. Substitute Romain Esse came close to scoring with his very first touch, but saw his shot blocked.
Esse was desperately unlucky later on, seeing one attempt crash off each posts before being clasped on the line. Uche also missed a sitter of a chance, indicating there is still room for development in his game.
The only worry for Palace was a late knock to Justin Devenny, who limped off. This paved the way for 17-year-old striker Benji Casey to earn his first-team debut, capping an otherwise positive night for the visiting side.
