Even though embarking on their maiden European adventure, Oliver Glasner's side are adapting very quickly. Missing key players like forward Jean-Philippe Mateta and wing-back Daniel Muñoz, the London club left Dublin with a commanding win that all but guarantees them a spot in the Europa Conference League playoffs.
Another three points in their upcoming match against Finnish KuPS ought to be sufficient to seal direct passage to the knockout stages, particularly after a prior setback against Strasbourg.
This match offered a chance for some of Palace's lesser-used players to shine. Christantus Uche, making only his second start since arriving on loan from Getafe, notched the account with a clinical finish. Forward Eddie Nketiah added a second, finding the net for the second consecutive succession.
The Shelbourne side that had finished their domestic season proved no match even for a mostly rotated Palace lineup. The Londoners were further depleted by the reports that Mateta and Muñoz are out with knee problems.
Despite torrential rain in Dublin, Palace quickly took control. A slick move in the 11th minute, initiated by Daichi Kamada's incisive pass, let Nketiah to lay on Uche for a straightforward finish.
Midfielder Adam Wharton went close minutes later, driving a long-range effort over the bar. Nketiah subsequently claimed for a penalty after bursting into the box, but the official dismissed the appeals.
The formerArsenal man didn't need to wait long to find his goal, prodding home from a yard out after Uche's shot had hit the post.
Shelbourne were hanging on desperately. Defender Kameron Ledwidge was lucky to avoid a booking for two agricultural challenges on Yeremy Pino, before Chris Richards rattled the woodwork with a header from a corner.
The match was effectively over eight minutes from half-time. Yeremy Pino weaved past some comically weak challenges before calmly slotting a shot past goalkeeper Wessel Speel to make it 3-0.
Following the break, manager Oliver Glasner took the chance to withdraw several individuals like Kamada and Wharton. Replacement Romain Esse almost scoring with his first touch, but saw his shot blocked.
The youngster was desperately unlucky later on, seeing one shot strike off both posts before being clasped on the line. Uche then blazed a glaring chance, indicating there is still room for development in his game.
The only worry for Palace was a second-half knock to Justin Devenny, who limped off. This paved the way for 17-year-old striker Benji Casey to earn his senior debut, capping an otherwise positive night for the traveling side.
