Analysis: West Ham 2-5 Arsenal
Before the game, optimism abounded at West Ham after their impressive win at Newcastle on Monday. The on-field announcers, sporting Christmas jumpers, were confident of a win.
That optimism was shot to pieces by an opening 35 minutes in which Arsenal were at times irresistable, but where West Ham were often their own worst enemies.
The marking for Gabriel's opener was sloppy, Lucas Paqueta's lazy trip on Bukayo Saka conceded a penalty, and it was 0-4 when Max Kilman failed to intercept a route one ball.
It meant West Ham never really looked likely to register back to back Premier League wins for the first time since March.
Manager Julen Lopetegui bought himself time with the Newcastle win, and the fans largely held off on booing in favour of backing the team.
But the Hammers cannot afford too many more hammerings like this.
