The Gunners still managed to get the better of fierce rivals Tottenham in midweek but face another tricky test against Aston Villa on Sunday, with youngster Ethan Nwaneri and star man Bukayo Saka still unavailable.
The visitors themselves are still missing captain John McGinn and a couple of first-choice defenders.
Elsewhere, Newcastle look in slightly better shape than Bournemouth as two of the league's in-form sides clash in the early kick-off on Saturday, while Manchester City's injury crisis seems to be nearing an end as their absentee list gradually grows shorter ahead of their visit to Ipswich.
See who's missing and who remains doubtful ahead of the next round of Premier League fixtures:
