Despite embarking on their maiden continental adventure, Crystal Palace are learning at a rapid pace. Without star figures like striker Jean-Philippe Mateta and defender Daniel Muñoz, the London club departed Dublin with a commanding result that all but secures them a place in the Conference League playoffs.
A further three points in their next fixture against Finnish KuPS ought to be sufficient to seal direct passage to the knockout stages, particularly following a prior setback against Strasbourg.
This match offered a platform for some of Palace's lesser-used players to shine. Christantus Uche, making only his second start since arriving on loan from Getafe, opened the scoring with a well-taken finish. Striker Eddie Nketiah added a another, finding the net for the second game in match.
A Shelbourne team that had concluded their league season proved outmatched against a mostly rotated Palace outfit. The visitors were already depleted by the reports that Mateta and Muñoz are sidelined with leg problems.
Despite heavy rain in Dublin, Palace rapidly established dominance. A flowing passing sequence in the 11th minute, sparked by Daichi Kamada's incisive pass, let Nketiah to set up Uche for a straightforward finish.
Midfielder Adam Wharton came close minutes later, driving a long-range effort over the bar. Nketiah subsequently claimed for a penalty after bursting into the area, but the referee waved away the appeals.
Ex-Arsenal striker did not have wait long to find his goal, tapping home from a yard out after Uche's effort had hit the post.
Shelbourne were hanging on desperately. Defender Kameron Ledwidge was lucky to escape a booking for a couple of robust challenges on Yeremy Pino, before Chris Richards struck the crossbar with a powerful header from a corner.
The match was effectively over eight minutes before half-time. Yeremy Pino meandered past some comically weak challenges before calmly dispatching a shot past goalkeeper Wessel Speel to extend the lead to 3-0.
After the break, manager Oliver Glasner seized the opportunity to rest key individuals like Kamada and Wharton. Replacement Romain Esse came close to scoring with his first touch, but saw his shot blocked.
The youngster was desperately unlucky later on, seeing one attempt strike off both posts before being gathered on the line. Uche then missed a glaring chance, indicating there is still room for improvement in his game.
The only concern for Palace was a second-half injury to Justin Devenny, who was forced off. This allowed 17-year-old forward Benji Casey to earn his senior debut, capping an otherwise perfect evening for the visiting side.
