Sage picks the same side that began Saturday's game against Ipswich, with Adam Wharton once again skippering the side in the absence of Dean Henderson.
Axel Disasi's suspension following his red card against the Tractor Boys only applies for domestic games, so he is able to take his place in defence.
As well as Disasi, there are European Palace debuts for Honest Ahanor, Anan Khalaili and Quinten Timber. Following his goal on Saturday, Jørgen Strand Larsen once again leads the attack.
As noted by Sage at his pre-match press conference, both Ismaïla Sarr and Eddie Nketiah are fit enough to take their place on the bench, the former is in the squad for the first time this season.
Academy midfielder Seb Williams is included in a senior squad for the first time, taking his place on the bench.
Jaydee Canvot returns to the matchday squad as a substitute, with Dwight McNeil and Ben Chilwell also available from the bench.
With Henderson’s injury ruling him out for 30 days, Remi Matthews temporarily replaces the goalkeeper in our official UEFA squad, as permitted by competition regulations. Academy 'keeper Lucca Benetton also takes a spot on the bench.
Palace: Benítez (GK), Ahanor, Richards, Disasi, Khalaili, Timber, Wharton, Mitchell, Pino, Kamada, Strand Larsen.
Subs: Matthews (GK), Benetton (GK), Canvot, Tomiyasu, Chilwell, Mingueza, Williams, McNeil, Osorio, Nketiah, Sarr.
