Southampton shut out a Premier League team in the League Cup yet again as they beat Liverpool 1-0 at home.
Nathan Redmond's first goal since October came in the 20th minute, and he could have had two or three more, with a late chipped effort bouncing agonisingly back off the crossbar.
Man-of-the-match Redmond, 22, said after the game "I should have had four today ... We got the clean sheet and the win so we take that on to the next game."
Liverpool were insipid throughout and failed to create with their usual electric regularity.
A rather bizarre moment came late on in the game, where Daniel Sturridge read a handwritten note from Jurgen Klopp when the match was live.
There was good news for the boys from Merseyside, however, in the shape of a fit-again Philippe Coutinho, who was injured in late November.
Jurgen Klopp said after the game: "We were not compact enough. We made the wrong decisions, that's how it is.
"They had the bigger chances ... it's a deserved win tonight for Southampton, but it's only half-time so, all good."
Southampton now travel to Anfield on January 25 as they look to make their way to Wembley for the final.
