Despite entering their maiden European adventure, Crystal Palace are learning at a rapid pace. Missing key players like forward Jean-Philippe Mateta and defender Daniel Muñoz, the London club departed Dublin with a comfortable win that virtually secures them a place in the Europa Conference League qualifying rounds.
Another victory in their upcoming match against Finnish KuPS should be sufficient to secure direct passage to the last 16, particularly after a previous setback against Strasbourg.
This match offered a platform for some of Palace's lesser-used talent to impress. Christantus Uche, making only his second beginning after arriving on loan from Getafe, notched the scoring with a clinical goal. Striker Eddie Nketiah contributed a second, scoring for the second consecutive succession.
The Shelbourne team that had concluded their league season proved outmatched even for a mostly rotated Palace lineup. The Londoners were already depleted by the reports that Mateta and Muñoz are out with knee injuries.
In spite of torrential rain in Dublin, Palace rapidly took control. A slick move 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 came close minutes later, fizzing a long-range shot over the bar. Nketiah then appealed for a penalty after racing into the area, but the referee waved away the appeals.
The formerArsenal man didn't need to wait long to get his goal, tapping home from a yard out after Uche's effort had hit the post.
The home side were clinging on desperately. Full-back Kameron Ledwidge was lucky to escape a booking for two robust tackles on Yeremy Pino, before Chris Richards struck the woodwork with a header from a corner.
The contest was effectively over eight minutes before half-time. Yeremy Pino meandered past a series of weak challenges before coolly slotting a shot past goalkeeper Wessel Speel to extend the lead to 3-0.
Following the break, coach Oliver Glasner seized the opportunity to rest key players like Kamada and Wharton. Replacement Romain Esse almost scoring his very first touch, but saw his shot blocked.
Esse was incredibly unlucky later on, seeing one attempt crash off both posts before being gathered on the line. Uche then blazed a sitter of a chance, showing there is still scope for development in his game.
A solitary worry for Palace was a late injury to Justin Devenny, who limped off. This paved the way for 17-year-old striker Benji Casey to earn his first-team debut, rounding off an otherwise positive night for the traveling side.
