The Gunners are relying on the competition to salvage their campaign, knowing that victory this weekend will secure them a place in next season's Europa League.
All focus is now on Saturday's showdown with London rivals Chelsea - a repeat of the 2017 final, which Arsenal won 2-1 at Wembley.
Here, Sports Mole looks at how Arsenal could line up in the showpiece fixture.
Arteta used a 3-4-3 formation in the semi-final win against Manchester City and that is likely to remain the case on Saturday.
Shkodran Mustafi injured his hamstring late on in that match and has been ruled out for three months, however, opening up a gap for Rob Holding to return to the backline.
Bernd Leno is back in training after a month-long layoff but Arteta has already confirmed that Emiliano Martinez will continue to operate in goal.
Elsewhere, Pierre-Emerick Aubameyang is expected to continue on the left of a front three and is looking to build in a return of three goals in two FA Cup final outings.
