Liverpool recorded a comprehensive 2-0 win over Chelsea at Stamford Bridge, with Sadio Mane netting a brace after Andreas Christensen was sent off for the hosts. Christensen was sent off towards the end of the first half for denying Mane a clear goal scoring opportunity. Referee Paul Tierney had first handed just a Yellow Card to the English defender, but after a VAR review, he changed his decision from yellow to red. Mane was released through on goal with an over the top ball by Jordan Henderson, and before the forward could take a touch and possibly try and round the keeper or chip the keeper, he was brought down by Christensen.Mane opened the scoring for Jurgen Klopp's side, heading home Roberto Firmino's pinpoint cross after some neat buildup by Liverpool. The Senegalese international then doubled Liverpool's lead after pressuring Kepa Arrizabalaga into giving away the ball inside the box, before slotting home.Chelsea were handed a lifeline when Thiago was deemed to have fouled Timo Werner inside the box, but Alisson made an excellent save to deny Jorginho from the spot.It started well for Chelsea and Werner...Timo Werner completed more take-ons (2) than all other players on the pitch combined (1) in the first 10 minutes against Liverpool.— Squawka Football (@Squawka) September 20, 2020Almost...Chelsea have failed to produce a single shot in the first 20 minutes against Liverpool.— Squawka Football (@Squawka) September 20, 2020But it all went south towards the end of the first half...RED CARD Andreas Christensen is sent off following a challenge on Sadio Mane, with the decision being confirmed after visiting the Referee Review Area Chelsea 0-0 Liverpool (45+1 mins) #CHELIV— Premier League (@premierleague) September 20, 2020Andreas Christensen is the first Chelsea player to be sent off in a Premier League game since Frank Lampard became manager.Time for the real test. https://t.co/b4bg5xhxCx— Squawka Football (@Squawka) September 20, 20202009 - Andreas Christensen is the first player to be sent off in a Premier League fixture between Chelsea and Liverpool since Frank Lampard in February 2009.
