Unai Emery will take no risks with the returning Laurent Koscielny as the defender nears a comeback after seven months out.
The centre-back has not featured for the first team since rupturing his Achilles in the Europa League semi-final second leg against Atletico Madrid in May, with the injury ruling him out of France's World Cup squad.
However, after a lengthy recovery period, Koscielny has lined up for Arsenal's developmental teams twice and, though he limped out of his last match late on, could be involved with the squad for Saturday's Premier League fixture with Huddersfield Town.
