The pair traded barbs last week over their approach to coaching.
And after victory over Real Betis, Mourinho said: "I think what Guardiola said is normal. What I said, and will say again tonight, is that I am an imperfect coach, but everyone knows what my imperfections are.
"I don't try to hide my defects. Others are capable of doing that and are more intelligent than me. We are all imperfect and I talk about the things I don't like when I see them. Others are more intelligent and only talk for themselves."
