Chelsea’s recent 3-0 defeat at Brentford has laid bare a series of defensive shortcomings that have plagued the club throughout the season. Manager Xabi Alonso lamented, "You need to feel it. We're not feeling it," after the loss, highlighting a familiar sense of frustration that has settled over Stamford Bridge.
This defeat marked Chelsea’s eleventh loss of the calendar year, a tally that already surpasses the total they suffered in the entire 2025 season, with three months still remaining. Moreover, the team has now allowed at least two goals in five consecutive Premier League matches under Alonso, and set‑piece vulnerabilities continue to haunt them. Alonso pointed out that the squad’s consistency and competitive edge evaporated in the second half, a concern that will resonate most strongly with the fans. Brentford capitalised on this dip in intensity, taking control of the game after the interval with relative ease.
The pattern of being out‑battled has become a recurring theme for Chelsea; last season they were outrun in the majority of their league fixtures, and that trend shows no sign of abating. Set‑piece deficiencies were a major talking point when Chelsea faced Brentford. The Bees excelled in long throws and cleverly executed corners, and, similar to the previous match against Hull, Chelsea surrendered another goal from a dead‑ball situation.
This was the fourth goal conceded from a set piece in five league games, raising their season total to 23 – the joint‑worst figure among all Premier League clubs. In the decisive moment, the ball was lofted directly onto Emiliano Martínez at the back post, and neither the keeper nor his defenders could react in time. Brentford’s preparation was evident; they anticipated the delivery well before it was taken.
Vitaly Janelt explained the tactical intent, saying to Sky Sports, "We targeted the back post at half‑time. There was a big gap at the far post, and we aimed for that on our first corner of the second half." Despite having Austin MacPhee, widely regarded as the league’s top dead‑ball specialist, Chelsea’s set‑piece execution remains erratic. Bernardo Cueva, the former set‑piece coach who now occupies a different role at the club, was even intercepted by Brentford during the match, underscoring the chaos surrounding Chelsea’s dead‑ball preparations. Levi Colwill echoed the sentiment of inadequacy, admitting that the team had been "bullied" at times and needed to improve.
He added, "We trust our set‑piece coach; we’re still adjusting to new ideas, but we must raise our overall standard as a unit." The set‑piece woes are only one facet of a broader defensive malaise. Chelsea’s ability to prevent opponents from penetrating the final third ranks among the poorest in the division, and the Blues have now endured 22 straight Premier League games without a clean sheet. Statistically, Chelsea concede an average of 2.2 non‑penalty goals per match, a figure that aligns closely with their expected goals (xG) against, indicating that the quality of chances they allow is genuinely dangerous. Their defensive frailties are further highlighted by the fact that they sit in the top three for shots conceded inside their own penalty area – roughly ten per game – forcing their keepers into a constant state of bombardment.
These defensive statistics help explain why Chelsea have struggled to protect leads in their last three league outings. The team often bursts out of the blocks with high intensity, yet this season they failed to take the lead within the opening ten minutes for the first time, only coming close when Pedro Neto saw a good chance saved.
When they do fall behind, the squad frequently reverts to familiar, unproductive habits. Alonso summed it up: "It’s about everything – mentality, football, and tactical aspects we need to improve. We concede the first goal, you’re still in the game, but then we lose shape.
We were out of control." Looking ahead, the return of Moisés Caicedo could provide some much‑needed stability in midfield, but the current lack of solidity without the Ecuadorian is worrying. Summer signings Jordan Henderson and Valentin Barco started the Brentford match, yet the Bees appeared stronger in the middle of the park. Brentford manager Keith Andrews arguably boasts deeper midfield options; his side won 3‑0 while record signing Mamadou Sangaré remained on the bench for over an hour. At present, João Pedro stands out as Chelsea’s most influential attacking player, but even his contributions could not prevent a goalless night – the first time this season that the Blues failed to find the net.
The transition period under Alonso is still ongoing; the starting XI featured seven of the club’s summer acquisitions, and he is only the fourth manager to take charge in nine months. Former captain Gary Cahill reminded Sky Sports that such overhauls take time: "It doesn’t happen overnight.
He’ll be judged over the next five, six, seven weeks because you’ll see his methods on the training ground and eventually in matches." Alonso broadened the scope of required improvements beyond set‑pieces, emphasizing defensive duels, build‑up play, and overall game control. In reality, those four areas encompass virtually every aspect of a modern football team’s defensive framework. Levi Colwill added that the squad has “a lot to work on over the international break,” a sentiment that will likely be echoed throughout the dressing room as they aim to tighten up before the season’s second half. The challenges are clear, the solutions are being crafted, and the coming weeks will be crucial in determining whether Chelsea can transform criticism into concrete progress.
