Rio Ferdinand and Sir Alex Ferguson enjoyed some incredible moments together at Manchester United.
Six Premier League trophies, three League Cups, a FIFA World Cup and a Champions League triumph during their 11 seasons.
So, picking his favourite memory of Ferguson must have been tough for Ferdinand.
However, the former defender didn’t pick a moment during one his many career highs with the Scottish manager but, in fact, the biggest low of his time under Ferguson.
That moment, of course, was when Ferguson’s side lost the Premier League on the final day of the season in 2012.
If that wasn’t tough enough to take, it was in the final minute.
But even more crushing was the fact it was to their local rivals, Manchester City.
The story of the day
If you don’t remember that incredible day on 13 May 2012, let us just remind you.
United had to better City’s result with the Red Devils travelling to Sunderland, while the Citizens hosted Queens Park Rangers.
It was supposed to be a formality. A simple win for City.
After 92 minutes, United had earned a 1-0 win and were waiting anxiously to discover the result of their rivals.
City had trailed QPR 2-1 in injury time but gave themselves a lifeline when Edin Dzeko scored in the second minute of injury time.
Ferguson and his players on the pictch at the Stadium of Light, just waiting official confirmation that they had won the title.
But in the 95th minute at the Etihad, Sergio Aguero scored a last-gasp winner to seal City’s first league title since 1968.
Ferdinand and his teammates were devastated and the Sunderland fans cheered deliriously and did the Poznan to celebrate City’s triumph and to tease the United players.
So, why was this Ferdinand’s greatest memory of Ferguson we hear you ask?
"His speech in changing room at Stadium of Light when we lost league to Man City.. Inspiring!” he said during a Twitter Q&A when asked of the greatest memory of his former manager.
While the 140 character limit on Twitter meant Ferdinand didn’t divulge into the details of Ferguson's speech, he mentioned it at the end of season just 24 hours after the crushing day.
"I'm a dinosaur. I'm an absolute dinosaur. But what I am, I'm a winner," Ferguson was quoted as saying, as per the Manchester Evening News.
"I said to all these players yesterday when we lost the league to Leeds United in 1992 the young players came out and all the Liverpool fans were asking the players for their autogrpahs. And they were tearing them up.
"I says to Giggs 'remember this day' and I said exactly to them yesterday: 'Those Sunderland fans that cheered for City, remember the day'. We won't forget that, I'm telling you."
