Liverpool made it through to the quarter-finals of the Europa League after a 1-1 draw with Manchester United at Old Trafford - winning 3-1 on aggregate after a 2-0 win at Anfield a week earlier.
Anthony Martial opened the scoring from the penalty spot after he was brought down by Nathaniel Clyne in the first half to give Louis van Gaal's side hope of an improbably turnaround, but Philippe Coutinho's wonderful strike on the stroke of half time stunned the home fans and dealt a sucker punch as it proved crucial to Jurgen Klopp's side progressing to the last eight.
It may not have been as convincing as their first leg performance, but United once again had David De Gea to thank for Liverpool not scoring more.
Here are five things we may have learned about Jurgen Klopp's side during last night's game:
Liverpool finding a knack of scoring huge goals at crucial times
If the scoreline is 1-0 at half time, then it could have been a very difficult second half for the Reds. Instead the strike on half-time just killed the tie unless they were going to help United in front of goal, and there was no chance of that happening. It's not the first time - just look at recent games against Manchester City and Crystal Palace where goals have come at crucial moments, either when the opposition may be getting on top or when they have no chance to reply.
Coutinho developing into a real match winner
Given that Liverpool were probably on the back foot a little, someone needs to step up with a moment of inspiration that can win a game - Coutinho did just that last night with his wonderful goal. It isn't the first time, he was the man that brought them on level terms in the League Cup final, has starred in big wins for the side at Chelsea and Manchester City notably. Whether it's his game, or his importance, something about the Brazilian has gone up a level this year.
Even when it doesn't particularly suit them, Liverpool thrive with an element of chaos
Liverpool may have preferred just a controlled manner and nothing particularly happening given the scenario of the game in the first half, but they seemed to relish how open and chaotic the game was at times. It may not have been good for the heart rate of their fans, but they get their fair share of goalscoring opportunities from them.
James Milner is Klopp's go-to man for every position
Jurgen Klopp had openly admitted that in hindsight it was a mistake not to select Jon Flanagan for the Europa League squad, so with the injury to Alberto Moreno he opted for James Milner in the role instead of the inexperienced Brad Jones. He played in the role during the closing stages of the League Cup final, but it's probably the sixth different position he's occupied under Klopp in one way or the other. One wonders when he's getting a chance in goal.
Daniel Sturridge starting to find some form even without scoring
Both Daley Blind and Chris Smalling looked very uncomfortable with Liverpool's front man prior to his withdrawal. Whenever he had them one-on-one, they seemed to be having kittens, he's finding that bit of confidence that could spark a goalscoring run, and seeing things not many other players see. That free-kick, most players don't look for that, and he was incredibly unlucky to hit the bar. There are a couple of other issues to iron out with linking up with teammates. He just needs to stay fit, then Liverpool's attacking unit could be frightening.
