Villa 3-2 – with an injury-time winner from debutant Federico Macheda – on 5 April 2009.
Party time: 16 May 2009, Old Trafford, United 0-0 Arsenal. Forgettable game but memorable scenes when Gary Neville lifted the trophy aloft in front of 75,468 fans.
Sir Alex said: "The challenge now is to win it next year. A 19th league title would be special."
Glory story: Propelled by a near-perfect home record, United see off the challenge of Arsenal and a late charge by title-holders Chelsea to secure a 19th championship on the penultimate day.
Top gun: Dimitar Berbatov, 21 league goals
Turning point: United were 2-0 down at West Ham on 2 April, but roared back with four second-half goals to stay in the driving seat at the top of the table.
Party time: 14 May 2011, Ewood Park, Blackburn 1-1 United. The Reds secured the point needed to become the most successful English league team with 19 titles.
Glory story: Spurred on by the heartbreak of losing the title in the dying seconds of the 2011/12 campaign and with the addition of one RvP to the squad, the Reds came back with a vengeance to secure a 20th title triumph... and with four games to spare.
Top gun: Robin van Persie, 25 league goals
Turning point: Last-minute victories at City and at home to Newcastle in December were important, but the second weekend in February when City lost at Southampton and United beat Everton (the team Sir Alex claimed we'd thrown the title away against the previous campaign) put the Reds 12 points clear and well in control of the title race.
Party time: 22 April 2013, Old Trafford, United 3-0 Villa. A first-half Robin van Persie hat-trick - the second goal of which was an absolute gem - secured the three points needed to seal title glory.
