Liverpool crept into a fourth Champions League quarter-final in five years despite a rare 1-0 defeat at Anfield to Inter Milan as the English giants progressed 2-1 on aggregate.
The Italian champions were unable to scale the mountain they had to climb after losing the first leg 2-0 at home three weeks ago despite Lautaro Martinez’s sensational strike into the top corner just after the hour mark.
Alexis Sanchez’s red card shortly afterwards punctured any Inter momentum and Liverpool comfortably held out with the extra man to take their place in the last eight.
Inter were left to rue conceding two late goals in Milan three weeks ago after they had enjoyed the better of the game for much of the first leg.
Klopp’s men failed to score for only the fourth time this season and fell to only a third defeat in 44 games in all competitions.
But their quest for a historic quadruple of trophies remains intact as Inter’s 10-men could barely get a foot on the ball in the closing stages, let alone muster another goal to take the game to extra time.
