Despite entering their first-ever European adventure, Oliver Glasner's side are learning very quickly. Without key figures like striker Jean-Philippe Mateta and wing-back Daniel Muñoz, the London club left Dublin with a comfortable win that virtually secures them a spot in the Europa Conference League playoffs.
Another three points in their upcoming match against Finnish KuPS ought to be enough to seal direct entry to the last 16, particularly after a prior setback against Strasbourg.
This occasion provided a platform for several Palace's lesser-used talent to impress. Christantus Uche, in only his second beginning since joining on loan from Getafe, notched the scoring with a clinical goal. Striker Eddie Nketiah contributed a second, finding the net for the second game in match.
A Shelbourne team that had concluded their domestic season proved no match even for a largely rotated Palace outfit. The Londoners were already weakened by the reports that Mateta and Muñoz are sidelined with leg problems.
In spite of torrential rain in Dublin, Palace quickly established dominance. A flowing passing sequence in the 11th minute, sparked by Daichi Kamada's clever pass, let Nketiah to lay on Uche for a straightforward tap-in.
Youngster Adam Wharton came close soon after, driving a powerful shot over the bar. Nketiah subsequently claimed for a penalty after bursting into the area, but the official dismissed the protests.
The formerArsenal striker didn't need to wait long to find his goal, prodding home from a yard out after Uche's effort had hit the post.
The home side were clinging on desperately. Full-back Kameron Ledwidge was fortunate to escape a booking for two robust challenges on Yeremy Pino, before Chris Richards struck the crossbar with a header from a corner.
The contest was as good as over eight minutes from half-time. Yeremy Pino weaved past a series of comically weak challenges before calmly dispatching a shot past goalkeeper Wessel Speel to extend the lead to 3-0.
Following the break, manager Oliver Glasner took the chance to rest key individuals like Kamada and Wharton. Replacement Romain Esse came close to scoring with his very first touch, only to see his effort blocked.
Esse was incredibly unlucky later on, seeing one shot crash off each posts before being clasped on the line. Uche then blazed a glaring chance, showing there is still scope for development in his game.
The only concern for Palace was a second-half injury to Justin Devenny, who was forced off. This paved the way for 17-year-old striker Benji Casey to earn his senior debut, capping an otherwise positive evening for the visiting side.
