#3 Sir Alex Ferguson (Manchester United) - 2013
Sir Alex is considered as one of the best managers to ever grace the game, if not the best. Although he had a successful spell at Aberdeen, he is remembered for his tenure at Manchester United where he was dominant for more than 25 years.
The Scotsman's final season at Old Trafford was the 2012-13 campaign, and it was a memorable one. United won the league title in dominant style, giving Fergie a special farewell. In doing so they won their 20th league title, going above arch-rivals Liverpool which made the victory even sweeter.
Sir Alex got an amazing farewell and deservedly so for the staggering 38 trophies he won at the club. What a manager.
