Diogo Jota netted the winner five minutes from time as Liverpool went top of the Premier League with their latest battling victory against West Ham.
David Moyes' side had taken an early lead at Anfield through Pablo Fornals before Mohamed Salah's penalty pegged them back.
Jota then collected a neat pass from fellow substitute Xherdan Shaqiri and finished to snatch the three points for his side after an earlier effort was disallowed.
Here are the headlines from Jurgen Klopp's post-match press conference, with the full transcript available on liverpoolfc.com.
On the role of Jota and Shaqiri
"It is not difficult to bring Diogo and Shaq on in the moment because they train in an exceptional shape, so it makes absolute sense that they get their minutes."
Liverpool's match-winning combination was an illustration of their depth in attacking areas.
Jota has already scored four goals since his summer arrival from Wolves, including three in the past seven days. In all, he is averaging a goal every 109 minutes under Jurgen Klopp.
And that will certainly be heaping the pressure on Roberto Firmino, whose end-product has dipped in recent times.
Shaqiri's return to fitness is also a boost for the champions, with the Swiss international showcasing his quality in his last two outings after spending much of the 2019/20 season on the sidelines.
Klopp appears optimistic that he has at last escaped his injury rut.
On Nathaniel Phillips
"He is a great guy, a smart guy, knows exactly everything about himself as a footballer. He kept it really simple tonight, which was incredibly important for us. The boys supported him well and he supported the boys; he was vocal and he spoke on the pitch."
After Fabinho was forced off with a hamstring injury in the Champions League, Rhys Williams was thrust into the spotlight.
Williams was subsequently tipped to make a first Premier League start on Saturday but that honour instead went to Nathaniel Phillips, who had impressed in the German second tier last season.
His performance was exemplary, prompting Sky Sports pundit and legendary Liverpool defender Jamie Carragher to select him as man of the match.
Klopp was grateful for Phillips' ability to do the defensive basics right and for his self-assurance.
On Liverpool's indomitable character
"The basis for all what we do and did is the character of this group, that’s how it is."
Since the start of last season, Liverpool have won 17 of their 45 games by a single goal, with nine victories from losing positions.
It is their capacity to grind out gutsy victories which has, above all else, been the foundation of their success.
Performances of late have been unconvincing, but ultimately, they have come through a period in which Alisson Becker, Virgil van Dijk, Fabinho, Joel Matip, Thiago Alcantara and Naby Keita have been injured with four wins from a possible four.
Their resilience again promises to be a vital asset.
On the level of fatigue
"It’s an incredibly difficult time - in the outside world, 100 percent, and for the boys as well. It’s really demanding, the number of games we have to play and that’s why... it still would be incredibly important if we could do that [make five substitutions] because you can only fight when your body is ready."
Perhaps one explanation for the Reds' sluggishness is fatigue. Most of their players, indeed, have been in action twice a week since around 20 September.
It is - in all respects - an exhausting season.
And Klopp again took the opportunity to suggest that the decision to revert to three substitutes may be detrimental to performance levels and to the footballing spectacle up and down the league.
On Curtis Jones
"Curtis Jones, for example, I don’t know how many starts he’s had, [but] he played an exceptional game tonight, not to forget how old he is."
It proved to be a footnote, but there was another show of faith in teenager Curtis Jones, who was handed his second start in three (significant) matches.
After a frustrating game against Ajax, Jones came up with a key contribution. His intelligent clipped ball to Salah put the Egyptian one-on-one with Arthur Masuaku, and he was able to draw a penalty.
Klopp was very impressed by the attacking midfielder's display, strengthening his 2020/21 prospects still further.
