Martin Tyler's guttural roar as Sergio Aguero found the net against QPR will never be forgotten. It's a moment of which Tyler said himself we'd never see the likes of again.
For a brief moment on May 13, 2012, Man Utd thought that they had won the league. Then, in the depths of injury time at the Etihad Stadium, the diminutive Argentine found the net with a strike past Paddy Kenny.
At the convention centre in Dublin last night, for a charity event along with Rory McIlroy, Fergie spoke about that day.
Man Utd had beaten Sunderland 1-0, a result which momentarily looked like was going to win them the league. On the Sunderland team was an old charge of Ferguson - John O'Shea.
The Ireland centre-back managed to play just 43 minutes as he tried to prevent his old side from getting the three points which could have brought yet another title to Old Trafford.
Stepping off the pitch and walking down the tunnel to the dressing room, Ferguson encountered O'Shea. The Waterford man was in an emotional state, still clearly feeling his connection with Man Utd.
When we lost the league to City, for 30 seconds we were champions. We actually thought we had won it and we were on the pitch until the Sunderland fans started chanting.
I went from half ready to celebrate to coming back into the dressing room. I'll always remember as we were going down the tunnel John O'Shea was standing there and he was almost crying. John was a Sunderland boy.
He said, 'Boss, what can I say?'
I had to brush by him as my mind was going 'What can I say to these boys of mine?'
I let them over it and I said, 'Right, anybody interviews you, you congratulate City. We're going to win it next year'.
