The result ended a spell of nine games without a victory and would have given the players some much needed confidence following a difficult couple of months.
Freddie Ljungberg's side must simply avoid a heavy defeat in order to be guaranteed of qualification, meaning that this game does not have any real pressure riding on it.
Here, Sports Mole looks at how the Gunners could line up for this game.
With Arsenal only needing to avoid a 5-0 defeat to qualify, Ljungberg can take the liberty of resting a number of key players ahead of the hectic Christmas schedule.
That said, the manager will be reluctant to take too many risks at the back given Arsenal's dire recent record at the back, and as such looks likely to start Shkodran Mustafi and David Luiz, who did not feature against West Ham.
Following injury to Tierney - the severity of which remains uncertain - it looks as if Sead Kolasinac will get a chance from the start at left-back.
Xhaka is set to miss this game due to suspected concussion, which means that Matteo Guendouzi comes into the team as a straight swap to partner Lucas Torreira, who has started in Arsenal's last pair of fixtures.
Willock and Nelson, despite their young age, are well versed in this competition, clocking up 21 Europa League appearances between them, while Saka has impressed down the left this season.
Linking it all together will be Pierre-Emerick Aubameyang, who was on the scoresheet again on Monday and seems to be undroppable in this kind of form. body check tags ::
