Liverpool have beaten Sheffield United 1-0 to continue their perfect start to the 2019/20 season.

But their victory came in incredibly fortuitous circumstances.

The Reds weren't anywhere close to their best and only a mistake from United goalkeeper Dean Henderson, which allowed Georginio Wijnaldum to score, gifted them all three points.

Bramall Lane was one of the three grounds that Liverpool had never won at before in the Premier League, and it looked like that record was going to be extended.

Liverpool struggled to impose themselves in the early exchanges, with a few loose passes suggesting they weren’t quite at it from the start.

The Blades, who recorded their first away win of the season against Everton last weekend, were giving a good account of themselves against the reigning European champions.

Liverpool were struggling to get Roberto Firmino into the game, with the hosts limiting the space that the Reds had to work with.

And Jurgen Klopp was growing frustrated.

The Liverpool boss could be seen on the touchline complaining to his defenders for passing the ball around too slowly.

And, with 30 minutes played, the home crowd started to really get behind their team, who were the better side.

However, it was Liverpool who should have opened the scoring.

Virgil van Dijk played a superb pass to leave Sadio Mane one-on-one with Sheffield United goalkeeper Henderson.

But Mane sliced his effort high and wide of the goal, when he should have made it 1-0.

The Senegalese forward then hit the post in the 43rd minute after being teed up inside the box by Firmino.

Mane entered the game with four league goals to his name and he missed two glorious opportunities to add to his tally before half-time.

Klopp’s team had 73% possession but couldn’t manage a single shot on target in the opening 45 minutes.

The German coach didn't make any changes, clearly hoping his message in the dressing room would do the trick.

But Sheffield United started the second half on top, with Oliver McBurnie heading over from a corner.

Liverpool required some interventions from Virgil van Dijk to thwart Chris Wilder's confident team.

There were suggestions that Liverpool could have earned a penalty when Mane was felled inside the area but he didn't appeal for it, and VAR didn't overturn referee Anthony Taylor's decision not to point to the spot.

Divock Origi was so often the hero for Liverpool last season and his services were called upon with 30 minutes remaining when he replaced Jordan Henderson.

But Sheffield United weren't ready to park the bus just yet and only a brilliant block from Robertson prevented John Fleck from scoring.

And then it happened. Liverpool scored.

Wijnaldum capitalised on an awful howler from Man United loanee Henderson to give the visitors the lead.

Wijnaldum's volley squirmed through Henderson's legs and rolled over the line.

How's your luck?

The goal prompted rival fans to argue just how lucky Liverpool are...

Liverpool held on to secure a vital win. 

This wasn't easy.
