The French tactician was involved in a minor scuffle with Mourinho after pushing him aside as he attempted to reach Alexis Sanchez who had been brought down in a rough challenge.
Mourinho did not however appreciate Wenger’s presence in his technical area, as Wenger pushed him aside, and when asked after the game if he regretted his actions, the Arsenal boss was quick to defend himself.
"No," he replied. "What is to regret after that?
"I wanted to go from A to B and somebody confronted me in between without any sign of welcome. B was Sanchez, to see how badly he was injured. Honestly, I don't listen to what [Mourinho] says."
Blues boss Jose Mourinho played down the incident, saying he did not want Wenger to influence the referee’s decisions on the pitch.
"For me, it is over,” said the Portuguese coach. “But the technical area is very clear - I have mine, he has his and he cannot come to mine, especially to put pressure on the referee to give a red card to my player.
"So I just told him 'leave my technical area and don't come back please'."
When asked if it was a big deal that Wenger had put his hands on him, Mourinho said, "No, it is no problem."
Wenger said he felt aggrieved by some of the refereeing decisions on the day, mentioning that a few Chelsea players were lucky to be on the field after the 90 minutes.
"I think Oscar was lucky to stay on the pitch with the repeated fouls he made," he said.
"He got a yellow card in the 88th minute and he was purposefully fouling on every break. [Branislav] Ivanovic as well. There were some bad fouls but that's down to the referee, it's not down to me."
The win sees Chelsea extend their lead at the top of the Premier league standings to five points, while Arsenal slipped down to eighth, eight points adrift of their London rivals.
