Alex Ferguson: Wife's grief prompted me to retire

Alex Ferguson has revealed he would have stayed on longer as Manchester United manager had it not been for the death of his sister-in-law.

The 73-year-old Scot shocked the football world in May 2013 when he announced his decision to stand down as United boss after 26 years in charge – having delivered the club’s 20th top-flight league title and 37 other trophies.
