Roberto Firmino and Mohamed Salah scored the goals for the home side after Wissam Ben Yedder had given the visitors a surprise early lead, but Joaquin Correa ensured the LaLiga side left with a point. And he was definitely an injection of attacking quality down Liverpool's left, but unfortunately he was also a bad defender.
The Merseysiders dominated and should have gone in at the break with a two-goal cushion, but Firmino saw his spot kick come back off the post.
Indeed, from false nine to genuine nine, Firmino is flourishing in the role and against Sevilla he displayed all the characteristics of the position.
But Firmino made no mistake in the 21st minute, the Brazilian converting from six yards after former Sevilla man Alberto Moreno's low cross eluded the defence and Rico at the near post. In the previous head to head record, past year in the UEFA Europa League Sevilla FC won the match against Liverpool.
Emre Can and Jordan Henderson were immediately out of position with the ball behind them as Sergio Escudero quickly resumed play. If the Reds are serious about making a challenge, they need to fix this issue soon.
He pressed into Sevilla players headlessly and it meant the back four was very often left exposed and without cover.

Jose Mourinho later confirmed Pogba's injury fears, but failed to explain its severity, saying: "I don't know honestly".
But after 37 minutes, Klopp's side did take a grip of the contest when Salah shot them ahead in fortunate circumstances.
In the Liverpool goal, Loris Karius relaxed. They were never going to match Liverpool on paper.
"It helped him that he could play tonight in the long-term, that's for sure".
Sevilla had just 7 shots and weren't really a creative force at all (only 3 of the shots were genuine attempts).
But despite Liverpool not winning on the night, Moreno can feel his own story was rectified, in part at least. For all the changes in the Andalusian team and dug-out since defeating Liverpool in the 2016 Europa League final, however, they remain a team with genuine European pedigree.
5' - GOAL! Liverpool 0-1 Sevilla.
It was one that spoke volumes, and will resonate with Liverpool fans jaded by the woeful defending that remains the overriding theme of Klopp era.
