Plymouth Argyle wrote one of the finest tales in their history book, and one of the darkest in Liverpool's, as the side bottom of the Championship beat the Premier League leaders in a famous FA Cup fourth round tie.
Ryan Hardie's penalty eight minutes into the second half - following a handball from Harvey Elliott - won the day for the Green Army, who delivered a superb rearguard display to keep out Arne Slot's much-changed side.
Liverpool struggled to create chances in a below-par display, with young midfielder James McConnell wasting a good late chance, and Conor Hazard might a superb late save from Diogo Jota.
Well Plymouth have solved that for them.
Liverpool face a huge couple of weeks in their quest to win the Premier League, but they won't be adding the FA Cup to it after this deserved defeat.
Arne Slot opted to leave many of Liverpool's star players at home.
For Liverpool much of the build-up to this game was dominated by interest in just which players would be present - or more accurately the ones who wouldn't be.
Ten changes were made from the side which beat Tottenham 4-0 in the Carabao Cup semi-final, but more importantly eight of those players who dropped out didn't even make the bench, with Slot opting to completely omit several stars who will start Wednesday's final Merseyside derby at Goodison Park.
It was a similar strategy to the one we saw him adopt in the Champions League tie at PSV Eindhoven, but with defeat there not coming with any consequence, this time it was certainly more of a risk, and so it proved.
