But he pointed out Gunner Eboue never said sorry for crocking Chelsea skipper John Terry in December.
"He is a mature guy and he apologised himself and no one forced him to. I always make the point of taking responsibility.
"Another player at Arsenal - whose name I will not say - tackled our captain who went to hospital and was out for a few weeks. He did not apologise. We are still waiting for that."
But Wenger hit back later in the day, saying: "Eboue's tackle on Terry was not a terrible tackle. I regret the injury to Terry but it was an accident.
"Perhaps Eboue could have eased off earlier but only he can tell you what was in his mind."
However, the Frenchman did acknowledge that former Gunner Cole - who will not be fined for his behaviour towards ref Mike Riley in Wednesday's 4-4 draw at White Hart Lane - was not a hatchet man.
Wenger insisted: "Ashley is not a dirty player."
