The image of Jurgen Klopp, frantically running down the touchline, gesticulating to Liverpool fans to raise the volume, encapsulated the thrill and flaw of a European run that ended in despair last night.

In his moment of need, with his side disintegrating as Sevilla transformed themselves from Tony Pulis’ Stoke to a La Liga pass and move hit squad, Klopp decided the most potent weapon was emotional support.

There was no change he could make from the bench, no tactical tweak to halt the Sevilla surge and no instruction to his players to delve into the darker arts to spoil the game for a few moments and take a breath.
