The Blues carry an unbeaten run into Wednesday’s Premier League clash against Tottenham Hotspur at Stamford Bridge and the Serb has been impressed with Mourinho’s ability.
“They call him ‘The Special One’, but I like to refer to him as ‘The Perfect One’,” he told Four Four Two.
“His results speak for him. I think that he is the most intelligent coach -he knows what he wants. He knows when to tighten up and when to loosen up.
“He knows what to demand from the team and from an individual player, and he knows how to deal with stress situations and to relax the atmosphere. It’s a pleasure and a privilege to work with him.”
Chelsea are also through to the next round of the Champions League, with one game to spare. Ivanovic admits it would be harder to win on the continent.
He said: “At this point we are in a good position in both competitions, but we are still a long way from winning them.
“The Champions League is a particular kind of competition – in the knockout stage a lot can depend on luck and freshness. I wouldn’t like to select which one to win, but I definitely would like a season with trophies.”
