The Frenchman said that he rated his compatriot Sagna at "80%" and revealed that Cazorla could also feature for the Gunners after shaking off an ankle injury.
"Sagna is 80% fit and he will have a test," Wenger told reporters.
"Cazorla is available in training but he is not match-fit. It is just about competitiveness with him. There is a possibility both are in the squad for Saturday.
"I have not decided whether they will start or not."
Meanwhile, Wenger is reportedly on the verge of signing a new contract at the Emirates.
