SHEFFIELD, England (AP) Liverpool relied on a dreadful goalkeeping error to take its winning run in the Premier League to 16 matches.
Georginio Wijnaldum's 70th-minute volley from the edge of the area went straight at Dean Henderson, only for the ball to squirm through the legs of the Sheffield United goalkeeper and gift the league leaders a 1-0 win at Bramall Lane on Saturday.
Henderson is on loan at the promoted club from Manchester United, traditionally Liverpool's fiercest rival.
Liverpool has opened the Premier League campaign with seven straight victories and has now won every league game since a 0-0 draw at Everton on March 3. Two more wins and Liverpool will tie the record of 18 straight Premier League wins, set by Manchester City in 2017.
Liverpool got away with one of its worst performances of the season, with Sheffield United in the visitors' faces all match and showing great intensity.
Jurgen Klopp's side did create the better chances, however, with Sadio Mane hitting the post from close range just before halftime and Mohamed Salah running through on goal in the 79th but seeing his finish turned aside by the right leg of Henderson.
United had an opportunity to equalize with five minutes left, but Leon Clarke lifted a shot over the crossbar as he stretched for a left-wing cross.
