With Partey missing, Albert Sambi Lokonga gets a first start since January.
Kieran Tierney is out for the rest of the seasona and, perhaps surprisignly, Granit Xhaka slots in at left-back over Nuno Tavares.
“Now he needs to react on that situation, because it is a great opportunity to learn a lot in that period in your career,” said Mikel Arteta this week.
Takehiro Tomiyasu is still absent as well with a calf issue and, as a result, Cedric Soares has kept his place at right-back.
Gabriel Martinelli is handed another start on the left wing after impressing off the bench during Monday’s defeat at Palace.
