The Frenchman accused O’Neill of intimidating referee Lee Mason at half time.
The Gunners boss said: “I know how it works here. At half-time the ref gets stick, in the second half a 50-50 decision goes the other way.
“I waited at half-time to see what happened and I was not disappointed.
“There is nothing more to explain. I had no discussion with O’Neill. You should ask him about that. The dugouts are close together.”
