In Premier League clash at Anfield on Saturday night and extend their unbeaten run at home to 62 games in the top flight.
Liverpool had to do it this time without injured defensive talisman Virgil van Dijk and at the end of a demanding week in which they drew 2-2 at Everton and ground out a 1-0 win over Ajax Amsterdam in the Champions League.
“A tough week obviously — a lot of games, a lot of minutes, tough opponents, hard-fighting opponents,” manager Jurgen Klopp said after the match.
“[We] won the two matches after the Merseyside derby, so really pleased with that, obviously.
“We didn’t score [the third goal] so the game stayed open and they had their moments, but we defended well with a big heart. And so I liked it.”
The visitors took a surprise early lead from the spot after VAR awarded Sheffield United a penalty against Fabinho and Sander Berge sent Alisson the wrong way to make it 1-0 inside of 15 minutes.
Alisson did well to keep the deficit at a single goal with an excellent reflex save, parrying away Ben Osborn’s smashing first-time volley in the 24th minute.
Liverpool then drew level shortly before half-time when Roberto Firmino side-footed into an empty net after Aaron Ramsdale’s save from a Sadio Mane header fell right in the Brazilian’s path.
Mohamed Salah looked to have put Liverpool in front just past the hour mark, but VAR once again intervened and the goal was ruled out for offside on the Egyptian as the match stayed level.
