Mikel Arteta has made one change to our side for our first taste of Champions League action this season, with Declan Rice coming into the team to face Athletic Club.
The England midfielder was rested for our 3-0 win against Nottingham Forest on Saturday, but returns to replace the injured Martin Odegaard.
With the Norwegian missing, Gabriel dons the armband, while his usual centre-back partner William Saliba is back amongst the replacements, with Cristhian Mosquera once again given the nod to start.
Christian Norgaard is named in a matchday squad for the first time after recovering from a knee issue and is on the bench, alongside another man awaiting his debut, Piero Hincapie.
