Arsenal host Chelsea in the Premier League on Wednesday as they attempt to regain momentum following Sunday's 1-1 draw at West Brom.
Koscielny's likelihood of playing is rated at 30 per cent by Wenger while Ozil is close to recovering from a knee problem and will be assessed.
Chelsea have no fresh injury problems for the trip to Arsenal, though defender David Luiz (knee) and forward Charly Musonda (groin) remain out.
Arsenal have had no offers for Mesut Ozil, Alexis Sanchez or Jack Wilshere, says Arsene Wenger, but the club are on the lookout for new signings
