Despite embarking on their maiden continental campaign, Oliver Glasner's side are learning at a rapid pace. Without key players like forward Jean-Philippe Mateta and defender Daniel Muñoz, the London club left Dublin with a commanding result that all but secures them a place 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 last 16, especially following a previous setback against Strasbourg.
This occasion offered a platform for some of Palace's fringe talent to shine. Christantus Uche, making only his second start after arriving on loan from Getafe, notched the scoring with a clinical goal. Forward Eddie Nketiah contributed a second, finding the net for the second consecutive succession.
The Shelbourne team that had concluded their domestic season proved outmatched against a largely second-string Palace lineup. The visitors were already weakened by the reports that Mateta and Muñoz are out with leg problems.
Despite heavy 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 simple tap-in.
Youngster Adam Wharton came close minutes later, driving a long-range effort over the bar. Nketiah subsequently appealed for a penalty after racing into the area, but the referee waved away the protests.
The formerArsenal man did not have wait long to get his goal, tapping home from close range after Uche's shot had struck the post.
The home side were clinging on desperately. Full-back Kameron Ledwidge was fortunate to escape a booking for two robust tackles on Yeremy Pino, before Chris Richards struck the crossbar with a powerful header from a corner.
The match was as good as over eight minutes before half-time. Yeremy Pino weaved past a series of weak challenges before coolly slotting a shot past goalkeeper Wessel Speel to make it 3-0.
Following the break, manager Oliver Glasner seized the opportunity to rest several individuals like Kamada and Wharton. Substitute Romain Esse almost scoring his first touch, only to see his shot blocked.
Esse was incredibly unlucky later on, seeing one shot strike off both posts before being gathered on the line. Uche also blazed a glaring chance, showing there is still scope for development in his game.
The only worry for Palace was a late injury to Justin Devenny, who limped off. This paved the way for 17-year-old striker Benji Casey to make his first-team debut, rounding off an otherwise positive evening for the visiting side.
