Even though embarking on their maiden European campaign, Crystal Palace are learning at a rapid pace. Missing star players like striker 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 Conference League qualifying rounds.
A further three points in their next match against Finnish KuPS ought to be sufficient to secure direct passage to the knockout stages, particularly following a previous setback against Strasbourg.
This occasion provided a platform for several Palace's lesser-used talent to shine. Christantus Uche, in only his second start after arriving on loan from Getafe, opened the scoring with a clinical goal. Forward Eddie Nketiah added a another, finding the net for the second game in match.
The Shelbourne side that had finished their domestic season proved no match against a mostly rotated Palace lineup. The Londoners were further weakened by the reports that Mateta and Muñoz are out with leg problems.
In spite of torrential rain in Dublin, Palace rapidly established dominance. A flowing move in the 11th minute, initiated by Daichi Kamada's incisive pass, allowed Nketiah to set up Uche for a straightforward tap-in.
Midfielder Adam Wharton came close minutes later, driving a long-range shot over the bar. Nketiah then appealed for a penalty after bursting into the area, but the official waved away the protests.
Ex-Arsenal man didn't need to wait long to get his goal, prodding home from a yard out after Uche's shot had hit the post.
The home side were hanging on desperately. Full-back Kameron Ledwidge was fortunate to avoid a booking for a couple of agricultural challenges on Yeremy Pino, before Chris Richards struck the woodwork with a powerful header from a corner.
The contest was as good as over eight minutes before half-time. Yeremy Pino meandered past some comically weak challenges before calmly slotting a shot past goalkeeper Wessel Speel to extend the lead to 3-0.
Following the break, manager Oliver Glasner seized the opportunity to rest several players like Kamada and Wharton. Replacement Romain Esse almost scoring his very first touch, only to see his shot blocked.
The youngster was desperately unlucky later on, seeing one attempt strike off each 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 concern for Palace was a second-half knock to Justin Devenny, who was forced off. This paved the way for 17-year-old forward Benji Casey to make his senior debut, rounding off an otherwise perfect evening for the traveling side.
