Oliver Glasner’s side beat Bosnian outfit HSK Zrinjski Mostar 2-0 on Thursday, and 3-1 on aggregate, to continue their European journey.
Maxence Lacroix headed Palace in front, before a late settler by January signing Evann Guessand secured the Eagles a spot in the next round, where they will play AEK Larnaca. If they beat the Cypriots, a potential quarter-final against David De Gea's Fiorentina is on the cards after that, although they have to overcome Poles Rakow Czestochowa first.
Last week’s 1-1 draw in Bosnia meant Glasner could take no chances, preventing him from rotating the team from their previous Premier League fixture.
