A new manager can change roles quickly, but defensive habits usually take longer to repair. Chelsea must improve the distances between their midfield and back line, reduce space in transition and show greater control without the ball.
The one-point return from three matches gives Alonso little room for another slow start. Bournemouth will test whether Chelsea can defend as a unit rather than rely on individual recoveries. A clean, disciplined performance would provide stronger evidence of progress than possession figures alone.
The challenge is particularly significant because the defensive concern is described as long-standing. That points to a structural problem, not one isolated error or poor result. Alonso’s first task is to establish a reliable base from which Chelsea can attack.
Caicedo’s fitness is being highlighted as crucial to Chelsea’s upcoming schedule. His ability to screen the defence, win second balls and support the first phase of possession makes him an important link between Alonso’s defensive demands and the team’s attacking ambitions.
If he is fit, Chelsea would have a natural midfield presence capable of protecting the centre during transitions. If he is unavailable or limited, Alonso may need to adjust the balance of the side, potentially placing greater responsibility on the surrounding midfielders.
That uncertainty makes the Bournemouth fixture more than a routine return. It is a test of both Chelsea’s depth and their ability to execute a clear defensive plan.
Chelsea do not need a perfect performance, but they do need visible improvement from the final three matches before the break. The next step is limiting avoidable openings and turning possession into territorial control.
Bournemouth will provide the first answer. The result matters, but Chelsea’s defensive organisation and Caicedo’s role may reveal more about whether Alonso’s project is moving forward.
