Chelsea’s recent 3-0 defeat at Brentford has laid bare a series of defensive problems that have plagued the club since Xabi Alonso took over. The Spanish manager’s post‑match comments – "You need to feel it. We're not feeling it" – summed up a season that feels all too familiar for Blues supporters. By the time the final whistle blew, Chelsea had suffered their 11th loss of the calendar year, a tally that already eclipses the total they recorded in the entirety of 2025, and there were still three months of league football left.
The pattern was unmistakable: for the fifth consecutive Premier League match under Alonso, the team surrendered at least two goals, and set‑piece vulnerabilities continued to haunt them. Alonso’s own analysis highlighted a loss of consistency and a missing competitive edge in the second half, a point that will undoubtedly worry the fanbase. Brentford exploited this dip in intensity with alarming ease, taking control after the break and never looking back. The broader trend is equally concerning – Chelsea have been out‑battled in numerous fixtures, echoing a season‑long issue where they were frequently outrun by opponents across the league.
One of the most glaring issues in the Brentford game was the handling of set‑pieces. From long throws to well‑rehearsed corners, Brentford’s dead‑ball routines proved decisive. Much like the previous encounter with Hull City, Chelsea lost their grip on the match when they allowed a set‑piece goal.
This marks the fourth time in five league games that the Blues have been penalised by a dead‑ball situation, taking their total to 23 conceded set‑piece goals since the start of last season – a figure that puts them joint‑worst among all Premier League clubs. The decisive goal came when a cross was delivered directly onto the back post, landing on top of goalkeeper Emiliano Martínez. Neither Martínez nor the surrounding defenders reacted in time, and Brentford’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, noting a noticeable gap that they exploited early in the second half.
Despite Chelsea’s appointment of Austin MacPhee – widely regarded as the league’s premier dead‑ball coach – the team’s set‑piece execution remains sub‑par. Former set‑piece specialist Bernardo Cueva, now serving in a different capacity at the club, was even poached by Brentford during the match, underscoring the depth of the issue.
Levi Colwill echoed the sentiment of frustration, stating that Chelsea have at times been "bullied" and must improve. He expressed confidence in the set‑piece coach but admitted the squad is still adjusting to new routines.
The set‑piece dilemma is only one facet of a broader defensive malaise. Chelsea’s ability to protect their own third is among the league’s poorest; the side has gone 22 straight Premier League fixtures without keeping a clean sheet. Statistically, they concede an average of 2.2 non‑penalty goals per game, a figure that aligns closely with their expected goals‑against (xGA) metric, indicating that the problems are not merely about bad luck but about systemic defensive weakness.
Compounding the issue is Chelsea’s propensity to allow a high volume of shots from inside their own penalty area. They rank in the top three for shots conceded inside the box, averaging roughly ten per match. This relentless pressure forces the goalkeeper into a perpetual barrage, effectively turning him into a battering ram.
Such exposure makes it virtually impossible for the team to preserve a lead, as evidenced by their inability to hold onto a advantage in their last three league outings. The opening stages of the Brentford match also highlighted a lack of urgency. For the first time this season, Chelsea failed to take the lead within the opening ten minutes, though they came close when Pedro Neto saw his chance saved. When they do fall behind, the team often collapses into familiar bad habits, losing shape and composure.
Alonso summed it up succinctly: "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 boost to the midfield’s defensive cover, but his absence has exposed the squad’s fragility. The two summer signings, Jordan Henderson and Valentin Barco, started the match, yet Brentford’s midfield appeared more cohesive and disciplined.
Brentford manager Keith Andrews arguably boasts greater depth in that area, and his side secured a comfortable 3‑0 win even with record signing Mamadou Sangaré remaining on the bench for most of the game. Offensively, João Pedro emerged as Chelsea’s most influential attacker in terms of goal contribution, but the famed "JP Morgan" front line was dismantled for the first time this season, and the Blues failed to find the net altogether. This underscores the broader transitional phase the club is undergoing. With seven new signings in the starting eleven and Alonso being only the fourth manager to helm the team in nine months, patience is essential.
Former captain Gary Cahill reminded Sky Sports that such transformations do not happen overnight. He suggested that Alonso will be judged over the next five to seven weeks, a period that should provide ample training time for his ideas to take root. Alonso himself broadened the scope of the required improvements beyond set‑pieces, citing defensive duels, build‑up play, and overall game control as critical areas.
In reality, those four elements – set‑piece defence, defensive duels, build‑up, and game management – encapsulate virtually every facet of Chelsea’s current shortcomings. Colwill added that the international break offers a valuable window to address these issues, a sentiment that resonates with anyone watching the Blues struggle for stability.
In summary, Chelsea’s defensive frailties are multi‑dimensional: a combination of set‑piece inefficiency, an inability to shield the penalty area, poor midfield protection, and a lack of mental resilience after conceding first. While the arrival of new coaching expertise and the reintegration of key midfielders like Caicedo provide optimism, the club must translate these resources into tangible on‑field improvements. The next few weeks will be decisive in determining whether Xabi Alonso can reverse the downward trajectory and restore the defensive solidity that Chelsea supporters have long expected.
