Even though embarking on their maiden European adventure, Oliver Glasner's side are adapting very quickly. Without star figures like striker Jean-Philippe Mateta and defender Daniel Muñoz, the Eagles departed Dublin with a commanding win that all but guarantees them a place in the Conference League qualifying rounds.
A further victory in their next match against Finnish KuPS ought to be enough to secure straight entry to the knockout stages, particularly after a previous setback against Strasbourg.
This match offered a platform for some of Palace's lesser-used talent to shine. Christantus Uche, making only his second beginning after joining on loan from Getafe, opened the scoring with a well-taken goal. Forward Eddie Nketiah added a second, scoring for the second game in match.
A Shelbourne side that had finished their league season were no match even for a largely second-string Palace lineup. The visitors were already depleted by the reports that Mateta and Muñoz are out with leg injuries.
In spite of heavy rain in Dublin, Palace quickly took control. A flowing move in the 11th minute, sparked by Daichi Kamada's incisive pass, allowed Nketiah to set up Uche for a straightforward finish.
Midfielder Adam Wharton came close soon after, fizzing a long-range shot over the bar. Nketiah subsequently appealed for a penalty after racing into the box, but the official dismissed the appeals.
The formerArsenal striker didn't need to wait long to find his goal, tapping home from close range after Uche's shot had struck the post.
The home side were clinging on for dear life. Defender Kameron Ledwidge was fortunate to avoid a booking for two agricultural tackles on Yeremy Pino, before Chris Richards rattled the crossbar with a header from a corner.
The contest was effectively over eight minutes from half-time. Yeremy Pino weaved past some comically weak challenges before calmly dispatching a shot past keeper Wessel Speel to extend the lead to 3-0.
After the break, manager Oliver Glasner seized the opportunity to rest several players like Kamada and Wharton. Replacement Romain Esse almost scoring with his first touch, but saw his effort blocked.
The youngster was desperately unlucky later on, seeing one attempt crash off each posts before being gathered on the line. Uche then blazed a sitter of a chance, indicating there is still room for development in his game.
A solitary concern for Palace was a late knock to Justin Devenny, who limped off. This paved the way for 17-year-old forward Benji Casey to make his first-team debut, capping an otherwise positive night for the traveling side.
