Mourinho revealed that he was set to step in Ferguson's shoes after the legendary manager ended his 27-year-old tenure, trophy-filled stint with the Red Devils in 2013 during a three-episode series titled 'Mourinho', which tells the story of the legendary manager's career

Mourinho said in the documentary "I think the objective of this work that we are doing [shooting a docuseries] is to tell the truth. When I left Real Madrid, I signed with Manchester United to go to Manchester United after Sir Alex [Ferguson]."

Ferguson, who announced that he would step down as Manchester United boss at the end of the 2012-13 season, said, "He [Mourinho] was offered a job, yes. I sat him down and explained the situation. And as far as I was concerned, he was accepting. And then within hours, it changed."

Mourinho then admitted that he was flattered by the offer, but decided to join Chelsea again as he "needed to feel that I'm loved" after an underwhelming run in Spain with Real Madrid.

"Evening he phoned me, and he was crying, and he says 'Oh, I cannot take it, I have given my word to Chelsea, and I'm not going to break my word,'" Ferguson said. "The reason he gave to me, I could understand. But I was disappointed," added Sir Alex Ferguson
