Jack Wilshere, Aaron Ramsey, Tomas Rosicky, Bacary Sagna and Kieran Gibbs all trained on Tuesday morning prior to the trip to Turkey.
Gibbs suffered a nasty cut over his eye during Saturday's 3-1 loss at home to Aston Villa but he has been patched up and Wilshere, who has struggled with injuries of late, seems to have come through 90 minutes on Saturday unscathed.
Sagna took a horrible-looking fall during Saturday's match, landing on his head, but has escaped a serious neck injury, and Ramsey and Rosicky have also shaken off knocks.
But Alex Oxlade-Chamberlain will miss the match and he is awaiting another scan on the potentially serious knee injury he suffered on Saturday.
"The difference from Saturday is that Oxlade-Chamberlain is out for a while with a knee problem," said Arsenal boss Arsene Wenger.
Wednesday's match is a vital one for Wenger, who is already under pressure after the season began with the disappointing loss to Villa.
Wenger said: "The pride of any football club is to win on the pitch and all the rest is less important. It is a tricky fixture in Turkey but we want to finish the job."
Fenerbahce v Arsenal is live on Sky Sports 1 on Wednesday from 7pm.
