Despite embarking on their maiden continental campaign, Crystal Palace are adapting at a rapid pace. Without star players like forward Jean-Philippe Mateta and wing-back Daniel Muñoz, the Eagles left Dublin with a commanding win that all but guarantees them a place in the Conference League qualifying rounds.
Another victory in their next match against Finnish KuPS should be enough to seal direct passage to the knockout stages, particularly following a prior setback against Strasbourg.
This occasion provided a chance for some of Palace's lesser-used talent to impress. Christantus Uche, in only his second start after joining on loan from Getafe, notched the account with a clinical goal. Forward Eddie Nketiah added a another, finding the net for the second game in succession.
The Shelbourne team that had concluded their league season were outmatched against a largely rotated Palace lineup. The Londoners were already depleted by the news that Mateta and Muñoz are out with leg problems.
Despite torrential rain in Dublin, Palace rapidly established dominance. A flowing passing sequence in the 11th minute, initiated by Daichi Kamada's clever pass, allowed Nketiah to lay on Uche for a simple tap-in.
Youngster Adam Wharton went close minutes later, driving a long-range effort over the bar. Nketiah subsequently appealed for a penalty after bursting into the area, 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 effort had struck the post.
The home side were hanging on desperately. Defender Kameron Ledwidge was fortunate to avoid a booking for a couple of robust challenges on Yeremy Pino, before Chris Richards rattled the woodwork with a powerful header from a corner.
The contest was effectively over eight minutes from half-time. Yeremy Pino meandered past a series of weak challenges before coolly slotting a shot past keeper Wessel Speel to extend the lead to 3-0.
After the break, coach Oliver Glasner seized the opportunity to rest several players like Kamada and Wharton. Substitute Romain Esse almost scoring with his very first touch, only to see his effort blocked.
The youngster was desperately unlucky later on, seeing one shot crash off each posts before being clasped on the line. Uche then blazed a sitter of a chance, indicating there is still scope for improvement 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 perfect evening for the visiting side.
