Sadio Mane scored twice as Kepa Arrizabalaga made another calamitous error in a 2-0 victory for Liverpool over 10-man Chelsea, with Thiago Alcantara conceding a penalty on his debut.
Frank Lampard’s side hardly laid a glove on the Premier League champions at Stamford Bridge and their cause was not helped by Andreas Christensen’s red card late in the first half, with Mane then scoring twice in the space of four minutes after the restart.
Mane’s second was a gift from the much-maligned Kepa, whose days as Chelsea’s first choice seem numbered with Rennes goalkeeper Edouard Mendy supposedly close to joining.
Thiago – who came on as a half-time substitute following his £20million move from Bayern Munich – marked his Liverpool debut by fouling Timo Werner to give away a penalty, but Alisson saved Jorginho’s spot-kick to cap a miserable day for Chelsea.
Kepa needed Christensen to block Roberto Firmino’s goal-bound flick after the goalkeeper left his line and was beaten to a loose ball by Mohamed Salah in the 13th minute.
Momentum swung in Liverpool’s favour on the cusp of half-time when Christensen brought down Mane and was sent off by referee Paul Tierney, who changed his initial decision to book the defender after a VAR review.
With new arrival Thiago thrown into the fray due to a reported thigh problem for Jordan Henderson, it took just five minutes for the Reds to make their numerical advantage count – Salah and Firmino combining to set up Mane, who headed in from six yards.
While Liverpool’s quality crafted their opener, their second was handed to them as Kepa’s pass was intercepted by Mane and he fired home.
Thiago’s clumsy tackle on Werner handed Chelsea a lifeline, but it was one Jorginho failed to take with his tame penalty easily saved by Alisson.
