Old Trafford is thought to have been Mourinho's desired choice for his second spell in the Barclays Premier League, only for Sir Alex Ferguson to recommend David Moyes as his successor.
In Diego Torres' book 'Prepare to Lose: The Mourinho Era', Mourinho is said to have sobbed when informed that Moyes would be taking over at United and viewed the decision as a betrayal by Ferguson.
The Premier League champions visit Stamford Bridge on Sunday and Mourinho insists he will be glad to take his seat in the Chelsea dug out.
"I think the person who wrote that book shouldn't write books. He should write books for kids using his imagination," Mourinho said.
"I am where I want to be. I want to go nowhere else. I have the job I want to have, I don't have another job.
"When I left Porto I wanted to come to England because at that time there was no Chelsea, I had no emotional connections with any club.
"When I left Chelsea I wanted only Italy or Spain, not another English club.
"After Real Madrid I wanted England and if possible, Chelsea. It's the only time I've said this country and this specific club.
"If not Chelsea then I'd have been in England at another club, but when the door at my club opened for me, I had the job I wanted to have."
Ferguson announced his retirement on May 8 last year with Moyes' appointment confirmed the following day, while Mourinho was named Chelsea manager for the second time on June 3.
"I knew a couple of weeks before the announcement because my friend (Ferguson) was very nice to me and trusted me completely," Mourinho said.
"He told me something really important before the press, he didn't want me to read it in the press. He told me you are one of my best players in football, I want you to know it from me.
"He was so nice to me, he gave me such a big reasonability to keep that.
"From me never, but I was afraid that somebody might leak it and the boss could think it came from me, so I was a little under pressure.
"In the same way he knew from me that I was coming back to Chelsea. It's just things between friends.
"I wasn't committed to Chelsea at the time, but I wanted to come and Chelsea had expressed the desire for me to come back."
United have struggled under Moyes and an 11-point gap has opened up between them and leaders Arsenal.
Asked if United would be seventh if he was in charge, Mourinho replied: "This is impossible to analyse. I'm not and because I'm not there is no point doing that.
"David is the right guy for the job. With the stability they are going to give him for sure, he will get results as a consequence of his quality and the club's stability."
