The match began with a flicker of hope for the home side when Lucas Paqueta unleashed a spectacular 25-yard strike that found the top-right corner, putting the Hammers ahead. However, Chelsea's response was swift and decisive. João Pedro equalized with a powerful header from a deft flick-on by Marc Cucurella, before turning provider for Neto to volley in the visitors' second goal from close range. The Blues extended their lead just before halftime when Estevao's excellent work on the right flank set up Fernández for a simple tap-in.
The second half brought no relief for West Ham. Moisés Caicedo capitalized on a costly error by goalkeeper Hermansen, who failed to handle a corner kick, to score Chelsea's fourth. The rout was completed by Trevoh Chalobah, who slotted home after another moment of defensive miscommunication in the West Ham penalty area, with João Pedro once again involved in the build-up.
The statistics from the game paint a clear picture of Chelsea's dominance. Their clinical finishing was reflected in a high Expected Goals (xG) of 2.93, while West Ham’s attack was largely ineffective, managing an xG of just 0.94.
For West Ham, the defeat marked a grim historical milestone, as they have now conceded eight goals in their first two top-flight games for the first time ever. The loss also puts further pressure on manager Graham Potter, who, with only nine points from his first ten home games, is the first West Ham manager in Premier League history to fail to reach double figures in that time frame.
Chelsea, meanwhile, celebrated a historic achievement of their own. This was just the 10th time in Premier League history that a team scored five or more goals in their first away game of the season. The Blues were also the last side to do so, a feat they accomplished just last season. The emphatic victory firmly establishes them as early contenders for the title.
