West Ham United are the first side to score more than one goal against Chelsea in a Premier League match in the 2021/2022 season, the Premier league has announced.
The league leaders left the London Stadium without a point, losing to their London rivals in a goal feast game.
Manuel Lanzini cancelled out Tiago Silva’s opener from the spot but Mason Mount restored Chelsea’s lead after being released by Hakim Ziyech.
Bowen brought West Ham back on level terms in the 55th minutes before left-back Masuaku gave the host the lead for the first time in the game and the eventual winner.
Chelsea have lost only their second game of the season and are level on points with Liverpool who defeated Wolves thanks to a late minute goal from Origi.
