Mourinho will continue to antagonise opposition benches by attempting to shake hands before the final whistle.
Aston Villa assistant manager Keane claimed a Sunday league boss would have floored Mourinho if he had done that.
Mourinho said: "First I want to say that I appreciate the comments (from Keane), I think that they are both two great examples of polite and well educated people. Because I am a humble guy trying to learn every day. I appreciate their comments.
Asked if he would understand why people would be upset: "No."
Asked if he would do it again, he replied: "Yes."
