The 2011-12 Premier League season is fondly remembered for the unforgettable events that occurred on May 13, 2012, the final day of the campaign.

Manchester City’s thrilling 3-2 victory over Queens Park Rangers is easily the finest moment since the league was established in 1992.

It was one of the times the term ‘you couldn’t write this’ actually applied.

Manchester United were within seconds of winning the title after defeating Sunderland 1-0 but Sergio Aguero stole the trophy from them with that last-gasp winner.

Sir Alex Ferguson considered that day as the lowest point of his Man United career.

“Of all the setbacks I endured,’’ Fergie said in 2013, per the Mirror, “nothing compared to losing the league to City. We were champions for 30 seconds.

‘‘When our whistle blew we were champions. Our players knew they had ballsed it up. There were no excuses.’’

Man United drew with Liverpool in October

Both Manchester clubs finished on 89 points but Roberto Mancini’s side had a superior goal difference. No doubt Fergie spent plenty of time looking back over United’s results and bemoaning the days they failed to pick up three points.

One of those days came in October when the Red Devils travelled to Anfield to take on Liverpool.

Man United required an 81st-minute equaliser from Javier Hernandez to secure a 1-1 draw in the game that sparked the race row between Luis Suarez and Patrice Evra.

What Suarez did before Gerrard's free-kick

Liverpool took the lead when Steven Gerrard steered a free-kick past David de Gea.

If you watch the free-kick back, the first thing you will notice is Ryan Giggs jumping out of the wall, allowing Gerrard a gap to fit the ball through.

So De Gea wasn’t helped by his teammates. But Suarez also played a part in the goal, attempting to confuse the Man United ‘keeper by dancing in front of him.

De Gea strained to watch the free-kick and barely moved as it bounced into the net. His reaction - one of complete fury - said it all.

Fergie explained Rooney's exclusion from starting XI

Wayne Rooney, who started on the bench, arrived as soon as Man United went a goal behind.

Ferguson would go on to admit that he questioned whether the forward was in the right state of mind following his red card for England against Montenegro days before the Anfield trip.

"He's obviously had a bad week with England,” the Scot said, per BBC Sport.

“He was very disappointed to be sent off and the three-match ban from Uefa makes it very difficult for England.

"He could miss all the European Championship. I wanted to have Wayne in the right state of mind.”
