Despite embarking on their maiden continental campaign, Crystal Palace are learning at a rapid pace. Without key figures like striker Jean-Philippe Mateta and wing-back Daniel Muñoz, the Eagles left Dublin with a comfortable result that virtually secures them a place in the Conference League playoffs.
A further victory in their next match against Finland's KuPS ought to be enough to secure direct passage to the knockout stages, especially after a prior setback against Strasbourg.
This match provided a platform for some of Palace's lesser-used players to impress. Christantus Uche, in only his second start since joining on loan from Getafe, opened the account with a clinical goal. Striker Eddie Nketiah contributed a another, scoring for the second consecutive match.
A Shelbourne side that had concluded their domestic season proved no match even for a mostly second-string Palace outfit. The Londoners were already weakened by the reports that Mateta and Muñoz are sidelined with leg problems.
Despite heavy rain in Dublin, Palace quickly took control. A slick move in the 11th minute, sparked by Daichi Kamada's incisive pass, let Nketiah to lay on Uche for a simple finish.
Youngster Adam Wharton came close soon after, driving a long-range shot over the bar. Nketiah then claimed for a penalty after racing into the area, but the referee dismissed the protests.
Ex-Arsenal man didn't need to wait long to find his goal, tapping home from close range after Uche's effort had hit the post.
Shelbourne were clinging on desperately. Defender Kameron Ledwidge was fortunate to escape a booking for two agricultural tackles on Yeremy Pino, before Chris Richards struck the crossbar with a powerful header from a corner.
The match was as good as over eight minutes from half-time. Yeremy Pino weaved past a series of comically weak challenges before coolly dispatching a shot past keeper Wessel Speel to make it 3-0.
Following the break, coach Oliver Glasner took the chance to rest several individuals like Kamada and Wharton. Replacement Romain Esse almost scoring his first touch, only to see his shot blocked.
Esse was incredibly unlucky later on, seeing one shot strike off each posts before being clasped on the line. Uche then blazed a sitter of a chance, showing there is still room for development 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 first-team debut, capping an otherwise perfect evening for the traveling side.
