The Real Madrid coach is now set to quit Spain having been dumped out of the Champions League last night by Dortmund.
Ivanovic told the Mirror: "Everyone at Chelsea cannot wait for the return of Mourinho.
"The players have had no confirmation that he is returning to Stamford Bridge, but we all want that to happen because it is one of the best coaches in the world."
Ivanovic believes the club would be a superpower under Mourinho. He added: "He is immensely respected by everyone and he has done well at the club in the past.<> "With him we can be stronger as a club, it would be another dimension of Chelsea and is sure to become one of the main competitors for the title."
