It's never a good time to lose to your rivals but Liverpool did just that last weekend when they went down to a 2-1 defeat to Manchester United at Old Trafford.
Two first-half goals from Marcus Rashford put the Red Devils firmly in control of the contest.
Jurgen Klopp's side pulled one back through Eric Bailly's own goal after the break, but they were unable to find a precious equaliser.
However, despite the 2-1 loss, a stat, albeit a highly obscure one, has emerged that will get Kopites very excited. So here goes.
The last time Liverpool lost 2-1 at Old Trafford in the league where the same player scored both of United goals and a United player scored an own goal, Liverpool went on to win the Champions League .
The game came in September 2004 when two Mikael Silvestre goals ensured a win for Sir Alex Ferguson's side over Liverpool, whose goal game courtesy of John O'Shea putting the ball in his own net.
Eight months later, Liverpool were crowned champions of Europe in stunning fashion with a memorable win on penalties against AC Milan .
And with Liverpool breezing into this season's Champions League quarter-finals after a 5-0 aggregate win over Porto last week, the prophecy is still alive for the current crop of Reds.
