Chelsea’s back‑line looks more fragile than ever, a fact that was brutally highlighted by Xabi Alonso after the Blues were thumped 3-0 by Brentford. "You need to feel it. We're not feeling it," the Spanish manager lamented, acknowledging a familiar sense of unease that has settled over the squad.
The defeat marks Chelsea’s eleventh loss of the calendar year – a tally that already exceeds the total they recorded in the entire 2025 season, with three months still to play. It also continues a worrying pattern: for the fifth consecutive Premier League match under Alonso, the team has surrendered at least two goals. The latest setback was compounded by a set‑piece disaster that underlined deeper defensive deficiencies.
Alonso was quick to point out the loss of consistency and competitive edge in the second half, a shortfall that will undoubtedly sting Chelsea supporters. Brentford seized the initiative after the break, dictating the tempo and leaving the Blues scrambling. This mirrors a broader trend from last season, when Chelsea were regularly out‑muscled and out‑run by their opponents, a habit that has yet to be eradicated.
Set‑piece vulnerability was the first thing that came to mind when the match began. Brentford’s long throws and intelligently designed corners proved lethal. Much like the previous game against Hull City, Chelsea’s defensive organization collapsed once again, yielding a goal from a dead‑ball situation.
In fact, this was the fourth goal they have allowed from a set‑piece in just five league fixtures, taking their total since the start of the previous season to 23 – the joint‑worst figure among all Premier League clubs. The decisive moment came when a cross was lofted directly onto the back post, landing squarely in front of Brentford’s striker.
Neither goalkeeper Emiliano Martínez nor the surrounding defenders reacted in time, and Brentford capitalised with a clinical finish. The irony was palpable: Brentford had identified the back‑post weakness well before half‑time, as midfielder Vitaly Janelt explained to Sky Sports, noting that they deliberately targeted the far post after spotting a gap. Chelsea’s set‑piece woes persist despite the appointment of Austin MacPhee, widely regarded as the league’s premier dead‑ball specialist.
Previously, Bernardo Cueva served in that role before transitioning to a different position within the club, and even he was poached by Brentford during the match. Defender Levi Colwill admitted to Sky that the team has been “bullied” at times and must improve, while also expressing confidence in the new set‑piece coach, acknowledging that the squad is still adapting to fresh ideas.
The defensive frailties extend beyond dead‑ball scenarios. Chelsea now sit among the worst in the division for allowing opponents to breach the defensive third, having gone 22 straight Premier League games without keeping a clean sheet.
Their average concession rate stands at 2.2 non‑penalty goals per game, a figure that aligns closely with expected goals (xG) data, suggesting that the quality of chances they allow is genuinely high. Compounding the issue is an alarming inability to protect the penalty area. Chelsea rank in the top three this season for the number of shots they concede inside their own box – roughly ten per match – turning their goalkeeper into a de facto battering ram. Such exposure explains why the team has struggled to preserve leads in their last three league outings.
In the Brentford game, Chelsea failed to assert themselves early, a rarity for a side that usually aims to dominate the opening ten minutes. They came close when Pedro Neto saw a promising opportunity saved, but the momentum never shifted in their favour. Once they fell behind, the team’s habitual loss of shape became evident.
Alonso summed it up: "We concede the first goal, you're still in the game but then we lose the shape. We were out of control." Looking ahead, the return of Moisés Caicedo could provide a much‑needed stabilising influence in midfield, yet his absence highlighted the lack of solidity the Blues currently possess. Two of the summer signings, Jordan Henderson and Valentín Barco, started the match, but Brentford’s midfield appeared more cohesive and energetic. Brentford manager Keith Andrews arguably enjoys greater depth in that area, as demonstrated by a 3‑0 victory despite leaving new signing Mamadou Sangaré on the bench for most of the game.
At present, João Pedro stands out as Chelsea’s most influential attacking player, but even his contributions could not break the deadlock. The ‘JP Morgan’ front line was dismantled for the first time this season, and the Blues failed to find the net altogether. Patience will be essential for Alonso as he continues to embed his philosophy at Stamford Bridge.
The current lineup features seven of his summer acquisitions, and he is only the fourth manager to take charge of the club in nine months. Former captain Gary Cahill reminded Sky Sports that transformation does not happen overnight, adding that Alonso will be judged over the next five to seven weeks as he implements his training methods and tactical adjustments. Alonso himself broadened the scope of the required improvements, stating that the team must work on defensive duels, build‑up play, and overall game control – not just set‑pieces. These four pillars encapsulate the core areas where Chelsea must evolve if they hope to climb out of the defensive mire.
Defender Levi Colwill echoed this sentiment during the international break, insisting that there is “a lot to work on” and that the squad must use the pause to address its shortcomings. The message is clear: without significant progress in both organisation and mentality, Chelsea’s defensive issues will continue to undermine any attacking ambitions they may possess.
