Nasri has been out of action since breaking his leg in pres-season in July.
Fabianski has been out since the start of the season following knee surgery.
“Nasri and Fabianski are very close to a return, I think after the international break,” Wenger said.
“We will see then, they will join training just before the break. Physically they will be short but once they join the group after the international break they will be fine.”
