Crystal Palace took the lead in the 36th minute when Maxence Lacroix headed home a cross from Adam Wharton. The second goal came in stoppage time, as Evann Guessand struck a right‑footed shot from the right side of the box to make it 2-0.
Both sides had chances, but Crystal Palace's set‑piece work and finishing proved decisive, while Zrinjski Mostar failed to convert any of their opportunities.
