Overview
- Kick-off is 17:45 GMT at Prague’s Fortuna Arena, with live coverage on TNT Sports 1 and streaming via discovery+.
 - Mikel Arteta confirmed Viktor Gyökeres is unavailable pending scans on a muscle issue, while Martin Zubimendi serves a one-game European ban.
 - Kepa Arrizabalaga did not train for the trip, so David Raya is expected to start in goal.
 - Academy forward Andre Harriman-Annous, 17, trained with the first team and has travelled, making him a potential late substitute option.
 - Arsenal have won all three Champions League games without conceding and are on a nine-match winning run; Slavia lead their domestic league, are unbeaten at home this season, and have two points in Europe.
