William Saliba and Gabriel Magalhaes will undoubtedly continue their formidable partnership in central defence, but Arsenal have problems at full-back. Takehiro Tomiyasu is out with a knee injury and on Friday, Arteta admitted that Kieran Tierney (hamstring), Oleksandr Zinchenko (calf) and Ben White (groin) faced a race against time to be fit.

Gabriel Martinelli meanwhile was recalled to the Brazil squad this month but missed training on Monday ahead of the World Cup qualifier against Peru. The Brazilian Football Confederation (CBF) later confirmed the Arsenal star was sent for an MRI scan to assess a calf problem.
