Even though embarking on their first-ever European adventure, Oliver Glasner's side are adapting at a rapid pace. Without key figures like forward Jean-Philippe Mateta and wing-back Daniel Muñoz, the London club left Dublin with a comfortable result that all but secures them a place in the Europa Conference League qualifying rounds.
Another victory in their upcoming match against Finnish KuPS should be enough to secure straight entry to the knockout stages, especially after a prior stumble against Strasbourg.
This occasion offered a chance for some of Palace's fringe talent to shine. Christantus Uche, in only his second beginning after arriving on loan from Getafe, notched the scoring with a clinical goal. Forward Eddie Nketiah added a second, scoring for the second consecutive match.
The Shelbourne team that had concluded their domestic season were no match against a mostly rotated Palace outfit. The visitors were further depleted by the reports that Mateta and Muñoz are sidelined with leg injuries.
Despite torrential rain in Dublin, Palace quickly established dominance. A slick passing sequence in the 11th minute, initiated by Daichi Kamada's incisive pass, let Nketiah to lay on Uche for a straightforward tap-in.
Midfielder Adam Wharton came close soon after, fizzing a long-range effort over the bar. Nketiah subsequently appealed for a penalty after bursting into the area, but the official dismissed the protests.
The formerArsenal man did not have wait long to find his goal, tapping home from a yard out after Uche's effort had struck the post.
Shelbourne were clinging on desperately. Defender Kameron Ledwidge was lucky to avoid a booking for two agricultural tackles on Yeremy Pino, before Chris Richards rattled the woodwork with a header from a corner.
The contest was as good as over eight minutes before half-time. Yeremy Pino meandered past some weak challenges before calmly dispatching a shot past goalkeeper Wessel Speel to make it 3-0.
After the break, coach Oliver Glasner took the chance to rest several players like Kamada and Wharton. Substitute Romain Esse almost scoring with his very first touch, only to see his shot blocked.
Esse was incredibly unlucky later on, seeing one attempt strike off both posts before being gathered on the line. Uche then blazed a sitter of a chance, showing 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 forward Benji Casey to earn his first-team debut, capping an otherwise positive night for the visiting side.
