As much as Liverpool fans ridicule Roy Hodgson, they have struggled against their former manager in recent years.
The Crystal Palace boss went into Saturday afternoon's game boasting the impressive statistic of never having conceded a single goal at Anfield as an opposing manager.
So, what many expected to be a routine home victory proved a lot more arduous.
For much of the first half, the Eagles sat back so deep that they rarely trespassed into Liverpool's half.
It was a tactic that could well have backfired, but with 34 minutes on the clock, it suddenly paid dividends.
Having arguably got away with a handball in their own box, Palace hit the hosts on the break and thanks to some nifty footwork from Wilfried Zaha, Andros Townsend opened the scoring.
You could hear the roars all the way from Manchester, where Pep Guardiola and co. will have been keeping a keen eye on proceedings ahead of their game against Huddersfield Town tomorrow.
However, the visitors' joy was relatively short-lived and almost immediately after emerging from the tunnel after half-time, Liverpool equalised through Mo Salah.
Roberto Firmino then put the Reds in front to seemingly turn the game on its head, before James Tomkins' leveller.
It does beg the question of what Jurgen Klopp said at half-time, given the way his side came flying out of the traps. One imagines the German will have had particularly stern words with Naby Keita, who really struggled in the first half playing in a more advanced position than usual.
Keita's poor challenge
The midfielder spent much of the initial 45 minutes on the wing and didn't look comfortable at all, as summed up by a moment of madness when he tried to get the ball off Townsend.
It was an incredibly late, dangerous challenge but remarkably, he got off scot free.
Referee Jon Moss didn't see the incident and that meant the Guinea international wasn't even booked.
Keita is a very lucky boy.
