Development duo Nya Kirby and Nikola Tavares kicked off a busy week of international action for Palace's representatives as both claimed wins on Wednesday.
Kirby came on in the 70th minute of England under-19s' 4-0 win over Moldova, as they started their Euro 2019 qualification tournament in fine style in Turkey.
The Eagles midfielder entered the fray with the Young Lions two-goals up thanks to strikes from Chelsea's Conor Gallagher and Danny Loader of Reading, and late on Bukayo Saka and Steven Sessegnon added further gloss to the scoreline.
Next up for Kirby and England is the second of three qualifiers against Iceland on Saturday morning.
His under-23s teammate Tavares also appeared for his country as a substitute as he featured for Croatia's under-20s in a 3-1 win against Belarus in Zagreb.
The centre-back came on in the 72nd minute to help his team clinch victory in the first of two friendlies against the same opponents, with the return game taking place away from home in Lucka on Friday.
Meanwhile, academy goalkeeper Oliver Webber didn't feature as Northern Ireland's under-19s also got their Euro U19 qualification campaign underway with a 0-0 draw against Poland.
