Chelsea's frailties at the back and on set pieces were on full display under manager Xabi Alonso as Brentford comfortably triumphed 3-0 in the West London derby. The Bees capitalised on every mistake, turning a routine corner into an early opening and later exploiting Chelsea's disjointed defence to seal a comprehensive win. The first goal arrived in the opening minutes when Brentford earned a corner from Mikkel Damsgaard.

Jannik Schuster rose to meet the ball and flicked it across the six-yard box, where an unmarked Jaidon Anthony met it with a precise header, sending the ball home from just a few yards out. The strike left the Blues stunned and set the tone for the rest of the match. Chelsea responded by pushing higher up the pitch, reshaping their shape into a back four in an attempt to create a level‑playing response.

The tactical shift, however, left them vulnerable to counter‑attacks. Brentford seized the opportunity when Kevin Schade broke through the midfield line, found himself one‑on‑one with goalkeeper Emiliano Martínez, and saw his shot saved. The rebound fell to Igor Thiago, who calmly slotted the ball home from close range, ending a personal drought of seven league games without a goal.

The final blow came deep into stoppage time. After a sustained period of pressure, Schade delivered a pinpoint cross to the far post, where Fabio Carvalho, making his first Premier League appearance since a long‑term injury, found space and tucked the ball away.

The goal marked Carvalho's return to scoring form and completed a 3-0 rout. Statistically, Chelsea have now allowed twelve goals in just five Premier League fixtures – the highest total in the division – and they are still searching for their inaugural clean sheet of the campaign. Their defensive record is a glaring concern, but the attacking output was equally disappointing. The side missed the services of the injured João Pedro, and his stand‑in, Danny Welbeck, failed to create any clear-cut chances.

Moises Caicedo's absence was also felt, with veteran Jordan Henderson stepping in for his first start against his former club, yet he could not influence the game positively. Cole Palmer showed flashes of brilliance, but overall the Blues struggled to generate sustained pressure.

The only notable chance came from Pedro Neto, whose ninth‑minute effort was comfortably saved by Brentford keeper Caoimhin Kelleher. Throughout the match, Chelsea's midfield appeared disjointed, and their forward line lacked the incisiveness needed to break down a disciplined Brentford defence. For Brentford, the victory represents another milestone: they are the first team this season to keep Chelsea from scoring. Their unbeaten run continues, propelling them to third place in the table.

The win also extends Chelsea's winless streak under Alonso to three league games, underscoring the urgency of a turnaround. Key moments of the match included: - 9': A save by Kelleher after Welbeck set up Neto in the box. - 41': Morgan Rogers' shot blocked by Schuster inside the penalty area.

- 50': Anthony's header striking the bar, with replays confirming he was level with the offside line. - 61': Brentford's opening goal, Schuster's header from Damsgaard's corner. - 82': Thiago's rebound finish after Schade's saved one‑on‑one.

- 94+4': Carvalho's late seal of the win from Schade's cross. After the match, Xabi Alonso addressed Sky Sports, expressing his disappointment: "I'm disappointed with the second half and with the result. This is not enough to compete in the Premier League.

We were not able to maintain our level for the full 90 minutes and that's why we were punished today. It's about everything – the mentality, the football and the tactical aspects that we need to keep improving. We can do much better." He also dismissed the notion of using João Pedro's injury as an excuse, insisting that the squad must collectively raise its standards. Brentford manager Keith Andrews also spoke to Sky Sports, highlighting the emotional roller‑coaster of football: "I think it's important that you enjoy these nights.

There's no point hiding it. There are some tough days in the game, and you've got to enjoy the different emotions.

I felt like there was something bubbling towards tonight. I have this unbelievable calm around the team because I trust them, so it's nice to see it come to fruition. I see humility and hunger within the group every day.

We're very respectful of each other, but we're going to get better. We have to continue improving in this league. We try to push boundaries and be really open with each other.

Let's continue on our journey because I'm loving it." Chelsea's defensive record now stands as the worst in the Premier League after just five matches, a statistic that will add pressure on Alonso to make immediate adjustments. The lack of cohesion in both the back line and the attacking third suggests deeper issues that need addressing, from set‑piece organization to the integration of new signings. Meanwhile, Brentford's confidence is soaring as they maintain their unbeaten start, and their ability to exploit opponents' mistakes could see them challenge for higher positions as the season progresses.
