Sir Alex Ferguson has revealed the biggest regret of his 26-year reign at Manchester United.
Ferguson transformed United from top-flight also-rans into the most successful club in English football history between 1986 and 2013.
The Scot experienced plenty of lows in addition to the highs, though, and has now admitted that he still feels guilty over dis-assembling one of his best squads at the beginning of the Premier League era.
