Xabi Alonso expressed his frustration following Chelsea's 3-0 defeat at Brentford, stating, "You need to feel it. We're not feeling it." This loss marks Chelsea's 11th defeat of the year, surpassing their total from 2025. Under Alonso, the team has conceded at least two goals in five consecutive Premier League matches, raising alarms among fans.

Key issues persist as Chelsea struggles with set-piece defense, conceding their fourth goal from set-pieces in five games. This has contributed to their total of 23 set-piece goals conceded since the start of last season, the worst in the league. Vitaly Janelt noted Brentford's intention to target the back post, leading to an easy goal from a corner.

Despite having the league's best dead-ball coach, Austin MacPhee, Chelsea's defensive woes remain. Levi Colwill acknowledged the need for improvement, stating, "We have not been good enough, at times we have been bullied."

The team's inability to maintain defensive shape is evident, with 22 consecutive Premier League games without a clean sheet. Chelsea averages 2.2 non-penalty goals conceded per game, reflecting their struggles to protect the penalty area. This lack of solidity is exacerbated by the absence of Moises Caicedo, whose return could provide much-needed stability.

As the squad adjusts to Alonso's methods, former Chelsea captain Gary Cahill emphasized the importance of the next few weeks for improvement. Alonso himself acknowledged that Chelsea must enhance their performance in defensive duels and overall game control. With the international break approaching, the team has significant work ahead to rectify their defensive shortcomings.
