Chelsea’s recent 3-0 defeat at Brentford has laid bare a series of defensive shortcomings that have become all too familiar for the Blues. As manager Xabi Alonso lamented, "You need to feel it.
We're not feeling it," the team’s lack of cohesion and confidence was evident throughout the match, marking yet another loss in a season that has already seen Chelsea suffer eleven defeats—more than they recorded in the entire previous calendar year. With three months still left in the campaign, the club’s trajectory appears increasingly precarious.
The most glaring statistic from the Brentford game is the continuation of a worrying trend: Chelsea have now allowed two or more goals in five consecutive Premier League fixtures under Alonso. This pattern is compounded by a persistent set‑piece problem. The Bees have now conceded four goals from dead‑ball situations in just five league games, taking their total since the start of last season to 23, which ties them for the worst record among all Premier League sides. In the Brentford encounter, a well‑executed corner saw the ball land directly at the back post, where Emiliano Martínez could not react in time, and the opposition capitalised with ease.
The goal was not a fluke; Brentford had identified the vulnerability well before the half‑time whistle. Vitaly Janelt, speaking to Sky Sports, admitted that Chelsea deliberately targeted the far post at the break, only to see the plan backfire as Brentford’s delivery was perfectly timed. Despite the presence of Austin MacPhee—widely regarded as the league’s most innovative dead‑ball coach—Chelsea’s set‑piece defence remains porous.
Bernardo Cueva, the former set‑piece specialist who now occupies a different role within the club, was even poached by Brentford, underscoring the depth of the problem. Young centre‑back Levi Colwill echoed the sentiment, stating that the team has been "bullied" at times and must improve its resilience. Beyond dead‑ball situations, Chelsea’s overall defensive organization is in disarray. The club has now gone 22 straight Premier League matches without keeping a clean sheet, a streak that highlights a systemic inability to protect the penalty area.
On average, the Blues concede 2.2 non‑penalty goals per game, a figure that aligns closely with expected goals (xG) data, indicating that opponents are consistently generating quality chances. Moreover, Chelsea rank among the top three teams for shots allowed inside their own box, with roughly ten attempts per match, turning the goalkeeper into a de facto battering ram. These defensive frailties have had a direct impact on the team’s ability to hold onto leads.
In their last three league outings, Chelsea have either surrendered a lead or failed to establish one early on. The Brentford match was the first Premier League game of the season in which Chelsea did not take the lead within the opening ten minutes, although they came close when Pedro Neto saw a clear chance saved. When the team does fall behind, a loss of shape quickly follows. Alonso summed up the situation succinctly: "We concede the first goal, you're still in the game but then we lose the shape.
We were out of control." The midfield battle also revealed shortcomings. Although summer signings Jordan Henderson and Valentin Barco started, Brentford’s midfield appeared more compact and disciplined.
Brentford manager Keith Andrews, who boasts greater depth in that area, fielded record signing Mamadou Sangaré for only a brief period, yet his presence on the bench underscored the gap in quality between the two sides. Offensively, the match highlighted another issue: the dissolution of Chelsea’s once‑formidable "JP Morgan" front line. Joao Pedro emerged as the most influential attacker in terms of goal contribution, yet the unit as a whole failed to find the net for the first time this season. This underscores the broader point that while Alonso’s attacking ideas have shown promise, his defensive blueprint remains embryonic.
Alonso is still in the early stages of imprinting his philosophy on Stamford Bridge. The starting XI featured seven of his summer acquisitions, and he is only the fourth manager to take charge of Chelsea in nine months. Former captain Gary Cahill reminded fans that transformation does not happen overnight, noting that Alonso will be judged over the next five to seven weeks as his methods begin to take root during training sessions. Alonso himself identified four key areas for improvement: set‑pieces, defensive duels, build‑up play, and overall game control.
While these categories are broad, they encapsulate the core of Chelsea’s current predicament. Colwill added that the upcoming international break offers a valuable window for work on these deficiencies. Looking ahead, the return of Moisés Caicedo could provide a much‑needed boost to the defensive midfield, potentially offering greater cover for the back line.
However, until the team resolves its set‑piece vulnerability, tightens its shape after conceding, and improves its ability to win duels, Chelsea is likely to continue slipping down the table. The next few weeks will be crucial in determining whether Xabi Alonso can turn this defensive crisis around or if the Blues will remain mired in a season of disappointment.
