Manchester United manager Jose Mourinho has revealed a secret Sir Alex Ferguson told him one month before announcing his retirement.

Ferguson has been United manager for almost 27 years and is regarded as the most successful manager of all time in the world of football.

The Scotsman retired when he was 72 years old, but his decision left all United fans and supporters worried about the club’s future.

The legendary manager kept it as his secret till 19 May 2013, but current United boss Mourinho has revealed that Ferguson told him the secret one month before the official announcement.

“He told me a huge secret not many people knew one month before the decision,” he revealed on Netflix’s ‘Alex Ferguson: Secret to Success’ documentary.

“I knew he trusted me because it was a huge decision. Finally, he told the media and it was a sense of relief for me.”

The day of his retirement in 2013, Ferguson revealed: “The decision to retire is one that I have thought a great deal about. It is the right time.”

“It was important to me to leave an organisation in the strongest possible shape. And I believe I have done so.”

“The quality of this league-winning squad and the balance of ages within it bodes well for continued success at the highest level; while the structure of the youth set-up will ensure that the long-term future of the club remains a bright one.”

Ferguson managed to win 38 trophies at Old Trafford, including 13 Premier League titles, five FA Cups and two Champions Leagues.
