Chelsea boss Jose Mourinho claims Manchester City rival Manuel Pellegrini is always "thinking about me".
Pellegrini accused Mourinho last month, among other things, of "always wanting to take credit for everything".
"When a manager is on holidays and still thinks about me, I have nothing to say," Mourinho said.
"I don't know (if he is obsessed with me). In my holidays I did zero interviews. Since I left London, zero.
"Yes, I still think about football. But I don't do any interviews, at least in that time. You are free of everything, questions, answers, controversy, interpretation, overreaction. You are free of everything. My holiday time - zero.
"If other guys use holiday time also for interviews, it's their problem."
