Sadio Mane scored twice as Kepa Arrizabalaga made another calamitous error in a 2-0 victory for Liverpool over 10-man with Thiago Alcantara conceding a penalty on his debut.
The Senegalese forward is only the third Liverpool player to score a Premier League brace at Stamford Bridge, after Steve McManaman in December 1995 and Philippe Coutinho in October 2015.
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 Renne goalkeeper Edouard Mendy supposedly close to joining.
