When it comes to the rivalry between Manchester United and Liverpool, there are few people who know more about it than Sir Alex Ferguson.
Although the Scot may not have been born in either North West city, as manager of United for 27 years between 1986-2013 he was in the thick of the action as the rivalry reached new heights in the Premier League era.
One man who shared many a derby day dressing room with Ferguson was former Red Devils striker Andy Cole. And, ahead of the latest United vs Liverpool clash set to take place this evening, he showed how much getting a win over their fierce rivals meant to Sir Alex by revealing how the legendary manager celebrated each victory.
In comments relayed on United's official website ahead of Monday night's kickoff, Cole explained how Ferguson couldn't help but break out into a dance when the three points were secured against Liverpool.
"The boss used to love it when we won and he'd always do a little jig! You knew straight away how much it meant to him."
Football fans will have memories of Alex Ferguson jumping for joy after big results in his earlier days at United, but the revelation that the Scotsman used to literally dance with delight makes us wish camera phones had been invented during Cole's time at Old Trafford.
Considering United enjoyed a pretty successful run against Liverpool during Cole's time at the club - winning nine of 20 meetings and drawing another six - there were plenty of Ferguson jigs to behold too.
If any Red Devils supporter was in doubt about how much the games against their regional rivals meant to their longest serving manager, another former player offered his insight in the run up to tonight's fixture.
Speaking to OmnipSport, former United winger Nani explained how Ferguson used to make clear just how important their fixtures against Liverpool were.
"Ferguson used to say that this is not just a game, it’s a challenge," he said.
"Everyone must win their battle against their opponent. We’re not just playing, we’re going out there to win.
"Win every ball, tackle, race, everything. Football comes last."
With only a few hours to go until kickoff, it remains to be seen which manager - Klopp or Mourinho - will be searching for his dancing shoes this time around.
