The Germany international picked up a knock during his nation's World Cup qualifier against Sweden in midweek.
"Ozil, Sagna and Cazorla are all fit," Wenger told the club's official website.
"Everybody else looks fit and ready. Cazorla is available in training, but he is not match-fit. It is just about competitiveness with him.
"There is a possibility both [Cazorla and Sagna] are in the squad for Saturday. I have not decided whether they will start or not."
Arsenal have won five of the six Premier League games that Ozil has played for the club.
