Xabi Alonso’s post‑match comments after Chelsea’s 3‑0 defeat at Brentford summed up the frustration that has been building at Stamford Bridge: “You need to feel it. We’re not feeling it.” The Blues have now suffered eleven losses in this calendar year – more than they recorded in the whole of 2025 – and with only three months left in the season the picture looks bleak. For the fifth consecutive Premier League fixture under Alonso, Chelsea have allowed at least two goals, and their vulnerability on set‑pieces has become a recurring theme.

Alonso lamented a loss of consistency and a missing competitive edge in the second half, a point that will undoubtedly worry the club’s supporters. Brentford seized the initiative after the break, and Chelsea never managed to regain control. This mirrors a broader pattern: the team is frequently out‑battled and out‑muscled, a problem that was evident in the majority of their league games last season when they were often outrun by opponents.

The immediate issue that stood out against Brentford was the handling of set‑pieces. Whether it’s a long throw, a clever corner, or a free‑kick, Chelsea have repeatedly surrendered possession and conceded goals.

In this match they fell victim to a set‑piece for the fourth time in five league games, raising their total since the start of last season to 23 – a figure that puts them level for the worst record in the Premier League. The decisive goal came when a cross was delivered straight to the back post, landing on Emiliano Martínez’s head. Neither the goalkeeper nor the surrounding defenders could react in time, and Brentford’s players anticipated the delivery with uncanny precision. Vitaly Janelt later explained to Sky Sports that the Bees had identified a gap at the far post during the half‑time break and deliberately targeted it with their first corner of the second half.

Despite having Austin MacPhee, who is widely regarded as the league’s top dead‑ball specialist, Chelsea’s set‑piece execution remains porous. Bernardo Cueva, the former set‑piece coach who now holds a different role at the club, was even poached by Brentford during the match, highlighting the internal turmoil surrounding this area of play. Levi Colwill echoed the sentiment of his teammates, admitting that the side had been “bullied” at times and needed to improve. He expressed confidence in the set‑piece coach, noting that the team was still adapting to new routines but that collective improvement was essential.

Beyond set‑pieces, Chelsea’s defensive frailties extend to open play. The club has now gone 22 straight Premier League fixtures without keeping a clean sheet, and they concede an average of 2.2 non‑penalty goals per match. Expected‑goals (xG) data suggests that this figure is not merely a product of bad luck; the Blues are statistically likely to allow roughly the same number of quality shots on target each game.

One of the most alarming statistics is Chelsea’s ranking among the top three teams for conceding shots inside their own penalty area – about ten per match on average. This relentless pressure forces the goalkeeper into a reactive role, often acting as a last‑ditch battering ram rather than a confident shot‑stopper. Such exposure makes it difficult for the team to preserve leads; in their last three league outings they have been unable to hold onto any advantage.

The opening stages of the Brentford game also highlighted a lack of urgency. For the first time this season, Chelsea failed to take the lead within the first ten minutes, though they came close when Pedro Neto saw a clear chance saved. When the team does fall behind, they tend to lose shape quickly, a habit that Alonso described as “out of control.” He stressed that the problem is multifaceted – it involves mentality, tactical discipline, and overall footballing philosophy.

The return of Moisés Caicedo could provide some much‑needed stability in midfield, but his absence has exposed a glaring lack of solidity. Two of the summer signings, Jordan Henderson and Valentin Barco, started the match, yet Brentford’s midfield appeared more cohesive and energetic.

Brentford manager Keith Andrews seems to have a deeper bench in that department, as evidenced by the fact that record signing Mamadou Sangaré spent over an hour on the bench while the Bees secured a comfortable 3‑0 victory. Offensively, João Pedro emerged as Chelsea’s most influential attacker in terms of goal contributions, but even his efforts could not break the deadlock. The ‘JP Morgan’ front line was dismantled for the first time this season, and the Blues were shut out – a first in the campaign.

It is important to remember that Alonso is still in the early stages of implementing his vision. This match featured seven of the club’s summer acquisitions in the starting eleven, and Alonso is only the fourth manager to take charge of Chelsea in nine months. Former captain Gary Cahill told Sky Sports that transformation does not happen overnight.

He believes Alonso will be judged on his progress over the next five to seven weeks, a period that should allow the team to train intensively and begin to see the fruits of his methods, especially on the attacking side of the game. Alonso himself acknowledged that the issues extend beyond set‑pieces. He highlighted the need for improvement in defensive duels, build‑up play, and overall game control – essentially the four pillars of a balanced football side. Levi Colwill added that the squad has “a lot to work on over the international break,” underscoring the urgency of addressing these shortcomings before the season’s final stretch.

In summary, Chelsea’s defensive crisis is multi‑dimensional, encompassing set‑piece vulnerability, an inability to protect the penalty area, poor midfield cohesion, and a lack of tactical discipline. The upcoming weeks will be crucial for Alonso and his staff to reverse this downward trend and restore confidence among the fans.
