Wenger had taken his Gunners side to Stamford Bridge to face the league leaders, only to see his side leave west London with a 2-0 defeat.
During the game, both managers clashed in the dugout, with the Frenchman pushing Mourinho during an argument.
And, although the 64-year-old admits that is 'not a way to behave on a football field,' he does feel the Blues boss antagonised him during the incident.
“They gave too much importance to this story. In hindsight I think I should not have reacted at all, it’s not a way to behave on a football field," Wenger told Telefoot.
"I always regret any signs of violence and I apologise but that’s part of games where everything is manic.
"And then we have quite a substantial past. Did Mourinho provoke me? That is how I felt. I did not enter Chelsea’s technical area.”
Chelsea are now five points clear at the top of the Premier League after their victory over the Gunners, while Wenger's men are nine points off top spot.
