Now in charge of Inter Milan, Mourinho told the News of the World: "While I was at Chelsea we did everything but win the Champions League. We won all the other big, big trophies. There was the first League title for Chelsea in 50 years and the next year we were champions again.
"My contract was until 2011, so I would have been there for seven years. It's enough time.
"And don't forget that as well as winning all those trophies in England, we got to two Champions League semi-finals in my three years.
"So we were going in that direction. We were very close. Then Chelsea decided to make a change and suddenly it was over. But I don't see it as unfinished business and I don't dwell on it. I had three great years at Chelsea.
"It was a special moment for me there, there was a special feeling and I had a passion for that club - I still do. I am proud I have left a legacy there that will survive for a long, long time. And I don't regret anything."
