Liverpool manager Jurgen Klopp admitted he was at a loss to explain his side's lacklustre performance during a 1-0 defeat to Southampton in the first leg of the League Cup semi-final on Wednesday.
Southampton, who created the majority of clear-cut chances, will take a slender advantage to Anfield courtesy of Nathan Redmond's 20th-minute strike but the outcome could have been a lot worse for Liverpool at St Mary's.
