With the busy winter schedule almost upon us, Arsenal fans know that they will need to dig deep into their squad in order to keep their season alive.
The Gunners have been relatively lucky with injuries so far this campaign but there are still some fitness issues that continue to haunt Arsene Wenger's team selections.
Santi Cazorla is the most notable long-term absentee but the likes of Shkodran Mustafi and Danny Welbeck have been forced to watch from the sidelines too recently.
Here is when we expect to see all of Arsenal's injured contingent back in action again.
Injury type: Hamstring strain
Out since: Limping off in the second half against Watford on October 14.
Expected return date: Manchester City (A), on November 5.
Injury type: Groin problem
Out since: Watford (A), October 14
Expected return date: Red Star Belgrade (H), on November 2.
What Wenger said: "Ospina is not very bad, he has a grade one [groin problem] so it's just a couple of weeks. He has a chance to be available against Belgrade."
Injury type: Achilles
Out since: October 2016
Expected return date: January 2018
What Wenger said: "The first signs are positive, but still he has not played for one and a half years.
"He is not in full training yet, he needs a few games with the reserve team. So I think if all goes well, it will be after Christmas."
