Mourinho says he agreed to replace Ferguson at Man Utd

"When I left Real Madrid, I signed to go to Manchester United after Sir Alex," the 63-year-old coach - now back at Real for a second spell - said in a new Netflix documentary series about his career.

The goalkeeper made 725 appearances across 25 years at Real, winning three Champions League titles and five La Liga crowns, but had spent much of the 2012-13 season on the bench.'The relationship I had with Jose was very cold' After taking over a struggling Real side, Mourinho helped them challenge the dominance of Pep Guardiola's Barcelona, winning La Liga, Copa del Rey and Spanish Super Cup trophies in his first two seasons at the Bernabeu.
