"Koscielny had a knock on his Achilles but he should be available for Saturday," he told reporters.
New signing Calum Chambers, a 20 million euro arrival, partnered Koscielny at Wembley and is expected to do so again on Saturday.
Wenger also confirmed that goalkeeper David Ospina, a summer purchase from Nice, is still a few weeks from being in a position to make his debut.
"Ospina is two or three weeks away," the Frenchman added. "He has a thigh strain from the Brazil versus Colombia game [at the World Cup]."
Wenger also confirmed the continued absences of Ryo Miyaichi, Theo Walcott, Serge Gnabry and Abou Diaby, though noting that Miyaichi is "very close" and that Diaby has returned to full training.
