May 2007. The day after beating Man City 1-0 at Eastlands, United were crowned champions when Mourinho’s men only draw 1-1 with Arsenal at the Emirates.
Sir Alex said: "Chelsea won the last two titles at a canter. We had to do something about it."
Glory story: United and Chelsea raced all the way to the final day before Sir Alex’s men won the title by two points. The Reds achieved a record Premier League goal difference of +58.
Top gun: Cristiano Ronaldo, 31 league goals
Turning point: Carlos Tevez’s 88th-minute equaliser at Blackburn on 19 April ensured it was still United’s title to lose – the Reds could even afford a defeat to Chelsea seven days later.
Party time: 11 May 2008, JJB Stadium, Wigan 0-2 United. Not even a downpour could dampen the Reds’ spirits as Ronaldo’s penalty and Ryan Giggs’ late sidefoot sealed the triumph.
Sir Alex said: "We’ve expressed ourselves in an entertaining way. The title is well deserved."
Glory story: United produced a classic home-straight surge to overtake Christmas leaders Liverpool in the table and thus equal the Merseysiders’ long-standing record of 18 titles.
Top gun: Cristiano Ronaldo, 18 league goals
Turning point: Coming back from 2-1 down to beat Aston 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.
