The Chilean refused to shake the hand of Mourinho after he celebrated by jumping into the crowd as Fernando Torres scored a late winner in the Blues' 2-1 win at Stamford Bridge but the Portuguese played down the incident, suggesting Pellegrini had the right to snub him.
"I don't feel it is a lack of respect," Mourinho said.
"If he was sad because of the result. I understand. If he was sad thinking that I was doing something wrong by going to celebrate there, I accept that too. No problem."
