So here is a delight for Manchester United fans who have been desperately missing their legendary manager's brand of football at Old Trafford in recent years.
Sir Alex was an inspiration to millions. His 'never give up' attitude was what kept him going for 26 long seasons at Manchester United's top job.
United fans have left no stone unturned to know about their longest serving gaffer.
However, here are a few facts the world barely knows about Sir Alex Ferguson.
#5 The Scot missed only three matches as United's boss
The former United boss was too professional when it came to his managerial job at the club. He never prioritised anything in his life over Manchester United.
Even today, the legend attends almost all the matches played by United. Sir Alex has missed only three matches over his 26 years spell at the club, as United's manager.
Once he had to leave for his son's wedding, another for the funeral of his brother's wife's and the last one to scout David de Gea in Spain.
Well, the third one surely paid off for the club.
