Chelsea’s recent 3-0 defeat at Brentford has laid bare a series of defensive shortcomings that have plagued the club this season. As manager Xabi Alonso lamented, “You need to feel it.
We’re not feeling it,” and the sentiment was echoed throughout the St. Louis Road crowd. This loss marks Chelsea’s eleventh defeat of the calendar year – already more than the total they recorded in the entire 2025 campaign – and it comes with three months of football still to play. For the fifth consecutive Premier League match under Alonso, the Blues have allowed at least two goals, and their vulnerability on set‑pieces has become a recurring theme.
Alonso’s post‑match comments focused on the team’s loss of consistency and competitive edge in the second half. “We dropped our consistency, our competitive mentality needed in the second half,” he said, highlighting a concern that will resonate most with supporters.
Brentford seized the initiative after the break, and Chelsea never managed to regain control. The pattern is familiar: Chelsea are being out‑battled across the pitch, a problem that mirrors their tendency to be outrun in many league games last season.
Set‑piece defending has been particularly problematic. The opening moments of the Brentford game reminded fans of the previous encounter with Hull, where a poorly defended corner led to a goal. In this fixture, the fourth goal conceded from a set‑piece in five league matches pushed Chelsea’s total since the start of last season to 23 – a figure that ties them for the worst record among Premier League clubs. The decisive moment came when a cross was placed directly at the back post, where Emiliano Martínez could not react in time, and the opposition’s players were already anticipating the delivery.
Vitaly Janelt later explained to Sky Sports that the team had specifically targeted the far post at half‑time, but the execution fell short. Even with Austin MacPhee, widely regarded as the league’s premier dead‑ball specialist, overseeing set‑piece routines, Chelsea’s problems persist. Bernardo Cueva, the former set‑piece coach who now holds a different role at the club, was even poached by Brentford during the match. Defender Levi Colwill admitted, “We have not been good enough, at times we have been bullied and we need to improve at that,” while also expressing confidence in the coaching staff’s ability to turn things around.
Beyond dead‑ball scenarios, Chelsea’s overall defensive structure is crumbling. The team has gone 22 straight Premier League games without keeping a clean sheet, conceding an average of 2.2 non‑penalty goals per match.
Expected‑goals (xG) metrics suggest that this figure is not merely a product of bad luck; the Blues are statistically likely to allow that many quality shots on target. Their inability to protect the penalty area is stark – they rank in the top three for shots allowed inside the box, with roughly ten attempts per game, turning their goalkeeper into a de facto battering ram.
These defensive frailties have directly impacted the club’s ability to hold leads. In their last three league outings, Chelsea have either surrendered a lead or never established one.
The Brentford game was the first Premier League match of the season where the Blues failed to score within the opening ten minutes, although Pedro Neto came close with a chance that was saved. When the team falls behind, they often revert to familiar, unproductive habits. Alonso summed it up: “It’s about everything – the mentality, the football and the tactical things that we need to keep improving.
We concede the first goal, you’re still in the game but then we lose the shape. We were out of control.” The return of Moisés Caicedo could provide some much‑needed stability in midfield, but his absence has highlighted a lack of solidity that the Ecuadorian’s presence normally mitigates. Two of the summer signings, Jordan Henderson and Valentin Barco, started the match, yet Brentford’s midfield appeared more cohesive.
Manager Keith Andrews’ side seems to possess greater depth in that area, as evidenced by their comfortable 3‑0 victory despite keeping new signing Mamadou Sangaré on the bench for most of the game. Offensively, João Pedro has emerged as Chelsea’s most influential scorer this season, but even his contributions could not prevent a goalless night – the first time the club has failed to find the net this campaign.
The match also marked the first occasion this season that the “JP Morgan” front line was broken up, underscoring the broader tactical challenges the team faces. Alonso’s task of instilling his philosophy at Stamford Bridge will not be resolved overnight. The starting XI featured seven of the club’s summer acquisitions, and the Spaniard is only the fourth manager to take charge in nine months.
Former captain Gary Cahill reminded the media that “it doesn’t happen overnight,” adding that Alonso will be judged over the next five to seven weeks as the squad has ample time on the training ground to embed his ideas. Alonso identified four key areas for improvement: set‑pieces, defensive duels, build‑up play, and overall game control. While set‑piece defending has been highlighted, the other three aspects are equally critical for a team that has struggled to maintain shape and composure.
Levi Colwill echoed this sentiment, noting that the squad has “a lot to work on over the international break.” The upcoming pause offers a chance for the Blues to regroup, refine their defensive organization, and return with a clearer sense of purpose. In summary, Chelsea’s defensive struggles are multi‑dimensional, encompassing poor set‑piece defending, an inability to protect the penalty area, a lack of midfield cohesion, and a fragile mentality when trailing. Addressing these issues will require a concerted effort from the coaching staff, the players, and the club’s leadership. Only by tightening up at the back, improving tactical discipline, and restoring confidence can the Blues hope to reverse their current trajectory and compete effectively for the remainder of the season.
