After the match, Pellegrini likened Chelsea's tactics to those of Stoke City, and Mourinho was keen to point out that it wasn't the first time the Chilean had spoken about his rivals.
"I don't have a reaction. I think [the media] should, not me. It was not once or two or three times that he said he doesn't speak about referees. He killed Mark Clattenburg [after City's draw at Arsenal]," Mourinho told reporters.
"It was not one, two, three, four times, he said he doesn't speak about me or my team's opponent. He did it once more. I think it's for you to comment. When I said I don't want to speak about him. That's what I try to do.
"If you want the story you have to speak with him not with me. I keep in my place. I follow my line."
Chelsea currently lead the way in the Premier League with 13 points from their opening five matches going into tomorrow's clash with Aston Villa.
