It ended up being a night for Mo Salah to savour, but it started with him on the bench.
Jurgen Klopp opted to rest the Egyptian from the start for an evening which threatened to be a concerning one for Liverpool before they blew Rangers away.
Salah's six minute hat-trick in the second half was the highlight of a stunning 7-1 win for the Reds, who started with a variation on their attack.
With Salah and Diogo Jota on the bench, the latter as a result of medical advice from Klopp's staff after he had been set to start, and Luis Diaz now out until after the World Cup with a knee injury, this really was all change.
Youngsters Harvey Elliott and Fabio Carvalho came into the side, and with the pair seen more as natural midfield players as opposed to forwards, the Liverpool formation took on more of a hybrid look between a 4-4-2 and 4-2-3-1 than an outright 4-2-4 that it sometimes looked at the Emirates.
There Salah, Jota, Darwin Nunez and Diaz all seemed to stand in a line on the edge of the Arsenal box at times, even just five minutes into the match and shortly after Arsenal had opened the scoring.
Here Carvalho and Elliott came a lot deeper though, at one point to Liverpool's detriment as it was Carvalho who lost the ball and allowed Rangers to spring and open the scoring through Scott Arfield.
But where the Portuguese youth international can be criticised there, he was the one of the attacking foursome who dragged the Reds back into the game, first firing a shot narrowly wide and then seeing another effort deflected out for a corner.
From that corner, Kostas Tsimikas' delivery was nodded in by Roberto Firmino for the most simple of equalisers, and a strike which has kept up his impressive and slightly surprising scoring form this season.
Operating behind Darwin, Firmino was looking to get on the ball in tight areas as he always has done, but he can be forgiven for wondering where the movement he has been so used to was in the first half.
That famed front three is no more of course, and he was often the conductor of that most pleasing three-man band.
He got his goal though and was looking bright, as was Elliott who drifted in from the right in central areas so often that, with Joe Gomez replacing the injured Trent Alexander-Arnold and struggling to get forward himself, the right flank was often left completely empty in an attacking sense.
Elliott almost teed Darwin up early on only for the flag to go up against the Uruguayan, who had opted to try and cross, and that summed up a first half for the summer signing which again saw him full of effort and application, only for the quality to let him down.
He can do worse than study Firmino when it comes to quality.
The Brazilian had been showing those signs of his quality in that first half, but in the second he absolutely dazzled as he first profited from Gomez finally getting forward to deliver a brilliant cross on a plate for him to fire home.
Then, after Darwin had blazed an effort over, he benefited from Firmino's brilliance as a superb touch fell into the path of the forward who superbly steered home.
That was his last act before being replaced by Salah, who of course then stole all the headlines with his stunning hat-trick, before Elliott got in on the act with the seventh on evening which turned into a confidence-boosting rout.
It may have been Salah's night in the end, but all of Liverpool's attackers took something from the evening.
