Mourinho will fight an FA charge after being sent to the stands in the closing stages of his side's defeat to Aston Villa last Saturday but he believes that he has received unfair treatment for his role in the incident sparked by a Ramires tackle on Karim El Ahmadi.
"Look, you see the charges from the last match, and you see that I'm different than everyone else in the eyes of people," the Portuguese coach told reporters.
"In their eyes, I'm different. That's obvious.
"Yes, it annoys me. Of course I am [treated differently]. I don't know why."
Mourinho's team host Arsenal in the Premier League on Saturday.
