Liverpool beat Leicester City 2-1 to post a fourth successive Premier League victory but conceded their first goal of the season after a nightmare mistake by new keeper Alisson, at the King Power Stadium, on Saturday. With Liverpool two goals up and cruising, the Brazilian failed to clear his lines and was robbed by Kelechi Iheanacho, who centred for Algerian Rachid Ghezzal to grab a goal back and set up a frenetic finish. Both Liverpool goals came before the break with Sadio Mane bagging his fourth goal of the season and Roberto Firmino heading home, from a James Milner corner. The visitors started the second half sloppily and, with Leicester threatening to grab another goal, a concerned Juergen Klopp brought on Xherdan Shaqiri for last season's record scorer Mo Salah. His changes worked and the visitors held on to confirm their best start to a season since 1990 and go top of the table ahead of Saturday's later kickoffs.
