Arsenal come into their Premier League game against Crystal Palace off the back of a 3-2 win over Portuguese side Vitoria de Guimaraes in the Europa League last time out.
The Gunners twice went behind but a header from Gabriel Martinelli and two stunning free-kicks from Nicolas Pepe earned their side all three points at the Emirates.
Arsenal's last Premier League performance ended in disappointment, however, as they slumped to a 1-0 defeat against Sheffield United and will be hoping to bounce back with a win.
Here, Sports Mole looks at how the Gunners could line up for Sunday's showdown.
Out: Reiss Nelson (knee)
Doubtful:
Unai Emery will be expected to name a fairly unchanged side following Arsenal's Europa League exploits in midweek.
The Spaniard has often made wholesale changes in cup competitions and has used the Europa League and Carabao Cup as an opportunity to hand recovering players such as Kieran Tierney, Rob Holding and Hector Bellerin valuable first-team minutes.
As such, it is likely that Bernd Leno will start with Sead Kolasinac, David Luiz, Sokratis Papastathopoulos and Calum Chambers ahead of him, while Granit Xhaka and Matteo Guendouzi form a midfield pivot.
Bukayo Saka and Thursday's hero Pepe are likely to start out wide again, although Dani Ceballos could be picked ahead of Joe Willock in support of Pierre-Emerick Aubameyang.
Alexandre Lacazette made his return from injury against Vitoria, but Emery may continue to be cautious with the Frenchman and ease him back from injury.
