Sir Alex Ferguson says he did not rule by fear at Manchester United, claiming he only used his infamous "hairdryer" treatment six times in his 27 years at Old Trafford.
Ferguson oversaw an unrivalled period of domination at United in which he led the club to 38 trophies, including two Champions League titles, before finally calling time on his reign in 2013.
The 74-year-old had a reputation for delivering verbal volleys at his players so intense it earned the nickname "the hairdryer," with Wayne Rooney saying in his book that there was "nothing worse" than experiencing it.
