Sir Alex Ferguson was a master of mind games during his time as Manchester United manager. Many opponents tried to take the Scot on and often came up short.
One of the men that tried to take on Ferguson was former Liverpool manager Rafael Benitez. The ex-Anfield boss had many spats with the legendary Old Trafford figure during his time on Merseyside.
However, the most infamous moment that came to define the battle between the two managers was the former Reds boss' famous 'facts' rant.

Liverpool were sitting pretty at the top of the Premier League in January 2009 when Benitez launched an incredible tirade towards Ferguson.
The stunt backfired incredibly and Manchester United went on to win the Premier League title, finishing four points ahead of their rivals.
In an interview with MSNBC's Morning Joe show, the 72-year-old said that moment 'killed' the now Real Madrid manager.
As per the Daily Mail, he said: "Knowing that I could handle press conferences because of the experience I had, I was always in control.
"I always made sure I came out the winner in a press conference, that was really important.
"And from time to time - like with Rafa when he had the sheet of paper with all his objections to myself and the club - it killed him because I didn't need to say anything after that. I said, "well, he must be troubled."
Former Liverpool captain Steven Gerrard has also admitted that he was embarrassed for Benitez following the rant.
Looking back, it completely dismantled Liverpool's title charge. The Reds were in brilliant form with Gerrard and Fernando Torres striking up a wonderful partnership.
It was arguably their best chance to end their long wait for a league title and the Merseyside club have only come close on one occasion since then - during the 2013-14 season under Brendan Rodgers.
