The Gunners ran out 5-2 victors at the Madejski Stadium on Tuesday night, with hat-trick hero Santi Cazorla the star of the show in a rampant Arsenal performance.
Lukas Podolski and Theo Walcott also struck for Wenger's side, who moved to within two points of the top four with the win.
Wenger felt talk of a crisis at the North London club, escalated by the Capital One Cup defeat at Bradford and reported rifts with assistant manager Steve Bould, was put to bed at the expense of bottom side Reading.
"Success came with the quality of our game. We focused on the quality of our game and played," he said.
"Our ambition is to finish as high as we can and win our next game, that is all we can do. We have to focus on the quality of our football."
When pressed on the recent harsh criticism of Arsenal, Wenger added: "It depends on what you mean by a crisis. If you call being slaughtered by everybody then we were in a super-crisis.
"In our job you need to be mentally strong. It is a test when you have been in a position like we were in."
