Arsenal have suffered in the absence of several key players in recent months, with the club exiting three cup competitions and drawing their recent Premier League games against Sunderland and West Brom.
However, Wenger believes that Fabregas, Song, Walcott and Diaby will all be able to take part in the game.
"They will all be available," he said on Thursday. "I have not decided if they will start the game yet but they will all be available."
"Van Persie has a good chance," he said. "He has a final assessment tomorrow but we believe he will be fit. It is a bruised knee.
"Nicklas Bendtner is in the same situation. He will have a test tomorrow on his ankle and we'll see. In fact, we have a few players with tests tomorrow - Ramsey with his groin, Bendtner with his ankle, Van Persie with his knee. I will make a decision after training in the morning.
"We just have Denilson out. It is short-term. We have one or two players with question marks but all the other players will be available."
