Arsenal's key injury concerns are manageable — Saka is out but Saliba is returning, and Viktor Gyokeres leads a deep attacking line. Slavia Praha were hammered 3-0 by Arsenal in this exact fixture 12 months ago, adding a revenge narrative that runs in Arsenal's favor. With Arsenal's squad quality and Slavia sitting at home as a significant underdog, covering a 1.5-goal spread against a side they've dominated historically is the clearest edge on the board.
