Mourinho, whose side were embarrassed by Basel in the Champions League in midweek, feels immune from pressure, despite working for one of the most ruthless owners in Roman Abramovich.
"I am not worried," he said. "I am came here to do my best, knowing that this team and squad would not be ready to achieve what people probably think we have to achieve.
"I was always told that my job this time would be a completely different job profile and I do my work the best way I can.
"I have maturity so that when I have a bad result or a defeat, I do not feel fragility or pressure.
"I know what I was told during the contacts with Chelsea before we decided to work together again, and I am the one who puts pressure on myself."
