LONDON (AP): Liverpool ended Chelsea’s unbeaten start in the English Premier League with a rousing 2-1 win yesterday. Keen to establish a high level of consistency, Liverpool backed up a 4-1 win over titleholders Leicester by outclassing Chelsea at Stamford Bridge, where the visitors posted consecutive wins for only the second time in 40 years. Liverpool, more energetic and inventive, was 2-0 up in about half an hour and controlled proceedings for an hour. Not until a leaping Diego Costa volleyed in a pass from Nemanja Matic to put Chelsea on the scoreboard did the match begin to feel competitive. But not for long, as Liverpool weathered Chelsea briefly coming out of their slumber, and returned to smothering the Blues. Only Manchester City and Everton remain unbeaten in the league. Chelsea dropped to third and Liverpool rose to provisional fourth to start the fifth round. Having already beaten last season’s league champions and runners-up, Liverpool’s third win in five games makes the second-round loss to promoted Burnley even more confounding. On Juergen Klopp’s watch, Liverpool have been strong against Chelsea, Arsenal, Tottenham, and the Manchester clubs, remaining unbeaten in six away games against them, and losing only once in 11 matches.
