Even though embarking on their maiden European adventure, Crystal Palace are adapting very quickly. Without star figures like striker Jean-Philippe Mateta and wing-back Daniel Muñoz, the London club departed Dublin with a comfortable win that virtually guarantees them a spot in the Europa Conference League playoffs.
Another victory in their next fixture against Finnish KuPS ought to be enough to seal direct passage to the knockout stages, particularly after a previous stumble against Strasbourg.
This occasion offered a platform for several Palace's fringe players to impress. Christantus Uche, making only his second beginning after arriving on loan from Getafe, opened the scoring with a well-taken goal. Forward Eddie Nketiah contributed a second, finding the net for the second consecutive match.
The Shelbourne team that had concluded their league season proved no match even for a largely second-string Palace lineup. The Londoners were already depleted by the reports that Mateta and Muñoz are sidelined with knee problems.
In spite of heavy rain in Dublin, Palace quickly established dominance. A flowing passing sequence in the 11th minute, sparked by Daichi Kamada's incisive pass, allowed Nketiah to set up Uche for a straightforward tap-in.
Youngster Adam Wharton came close soon after, fizzing a long-range shot over the bar. Nketiah subsequently appealed for a penalty after bursting into the box, but the official dismissed the protests.
The formerArsenal striker did not have wait long to find his goal, prodding home from close range after Uche's shot had hit the post.
The home side were clinging on for dear life. Full-back Kameron Ledwidge was lucky to escape a booking for a couple of robust challenges on Yeremy Pino, before Chris Richards rattled the crossbar with a powerful header from a corner.
The match was effectively over eight minutes from half-time. Yeremy Pino meandered 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 took the chance to rest key players like Kamada and Wharton. Replacement Romain Esse almost scoring with his very first touch, but saw his effort blocked.
Esse was desperately unlucky later on, seeing one shot crash off each posts before being clasped on the line. Uche then missed a sitter of a chance, indicating there is still room for development in his game.
A solitary worry for Palace was a late knock to Justin Devenny, who limped off. This allowed 17-year-old striker Benji Casey to earn his senior debut, capping an otherwise positive night for the visiting side.
