"Sagna will not be fit. He has a hamstring injury and will be out for three weeks," he said at his pre-match press conference ahead of Sunday's clash with West Brom.
He added: "Everybody else came out of the Napoli game without a major problem so they should all be available."
The Gunners will still be without Santi Cazorla and summer signing Yaya Sanogo, due to injury, but Wenger is confident they will be back in first-team contention soon.
"[Cazorla] is not in contention. But he could be not far after the international break," he added.
"He is [Sanogo] on a good way after his back problem. He will be the same, after the international break."
