You'd have to go back a long time to find a result as bad as Liverpool's opening period at the Emirates.
Liverpool fans will be disappointed enough at the fact their Champions League dreams may be over after their side lost 4-1 to Arsenal, but to help provide some extra gravity to quite how big a defeat it was, you need a little help from the history books.
Because the first half against Arsenal at the Emirates on Saturday afternoon was Liverpool's worst performance for over 21 years.
Not since Valentines Day 1994 had Liverpool gone in at half-time three goals or more behind the opposition in a league game.
You'd have to go all the way back to February 14 that year, when the Merseyside giants visited Southampton, to find a result as poor as they managed in North London.
In that game, Liverpool went 3-0 down in the first half courtesy of a Matt Le Tissier double and a strike from Craig Maskell. Le Tissier went on to complete his hat-trick after the break by scoring his second penalty past Bruce Grobbelar, before Julian Dicks scored his own spot kick and Ian Rush grabbed another consolation late on to see the Reds leave the Dell as 4-2 losers.
Liverpool, managed by Roy Evans, finished 8th that season, and they have twice finished that low in the 21 years since, but Brendan Rodgers and his side will be devastated at the fact his players had put together such an impressive run in 2015 to pull them right back into the Champions League race from mid table mediocrity, only for successive losses against the very teams they had been chasing down, their only two defeats in the league this year, seemingly ruling them out of the running.
Halftime deficits of 3-0, somewhat famously, haven't deterred Liverpool in other competitions in recent times, and despite a brief moment of hope after Jordan Henderson converted a second half penalty, it would be the three goals in 8 first half minutes that would prove insurmountable, especially after Emre Can was dismissed. Those first half strikes from Hector Bellerin, Mesut Ozil and Alexis Sanchez seemed to really shock the Reds in what had been an open first half, and it was Olivier Giroud who had the final say when he netted Arsenal's fourth in injury time.
It now looks like Liverpool will be battling for fifth place with Southampton and Tottenham, with all three having flirted with the idea of seizing that coveted top four spot at one point or another this season.
If it's any consolation for Liverpool fans, the season after 1993-94, they managed that fourth placed finish.
