Arsenal will make late checks on the fitness of forward Gabriel Martinelli and full-back Oleksandr Zinchenko for their home Europa League game against Dutch side PSV Eindhoven on Thursday.
Martinelli played throughout Sunday's 1-0 victory at Leeds, but Zinchenko has missed four matches with a calf injury.
The Gunners would reach the knockout phase with a draw, while victory would take them close to winning Group A.
This game was due to be played on 15 September but was postponed because of "severe limitations on police resources" following the death of Queen Elizabeth II.
