Chelsea's Defensive Woes: Anselmino and Sarr Injured in Pre-Season Friendly

Aaron Anselmino left the pitch in Johor with tears in his eyes and a hamstring that could reshape Chelsea’s early season.

Just 29 minutes into a pre-season friendly at Stadium Sultan Ibrahim, the 21-year-old centre-back pulled up and went down, clutching the back of his leg. He stayed there for a long time, flat on the turf, treatment staff hovering, team-mates gathering. When he finally rose and made the slow walk to the touchline, he did so in visible distress, consoled by colleagues who know exactly what this might mean for him.

For Anselmino, this is not a one-off scare. Since arriving at Stamford Bridge in 2024, the former Borussia Dortmund and Strasbourg loanee has been stalked by fitness problems of a similar kind. Each time he has tried to edge closer to the first team, something has tugged him back. This latest setback lands at the worst possible moment, just as he was trying to convince Enzo Maresca’s successor, Alonso, that he could be trusted as a genuine option in central defence.

The emotion on his face told its own story. This was not a precautionary stroll down the tunnel. It looked like a player who knows his body and fears what it is about to tell him.

Defensive plans unravel before kick-off

Alonso’s problems started before a ball had even been kicked.

Mamadou Sarr, the 20-year-old Senegalese centre-back, was named in the starting XI but never made it to the first whistle. He pulled out during the warm-up, leaving Chelsea to rip up their defensive plan on the fly. One young defender lost before kick-off, another inside half an hour. A friendly in Malaysia turned into a grim roll call for the medical team.

This is not a squad brimming with spare millions for late-window fixes at centre-back. After a summer of heavy spending in other areas, the expectation around Cobham was that Alonso would lean on the depth already in-house. Players like Anselmino and Sarr were supposed to be the safety net, the flexible options who could absorb the strain of a long season.

Losing both in the same afternoon doesn’t just hurt the bench. It forces a rethink of the entire defensive strategy.

Chaos on the touchline

The drama was not confined to the treatment room.

On the touchline, Chelsea’s new-look coaching staff found themselves dragged into the spectacle. A dangerous challenge on Liam Delap sparked a flashpoint with the opposition bench, and set-piece specialist Austin MacPhee surged forward in anger. Alonso had to physically restrain him, arms out, hauling his colleague away as tempers flared.

It was an ugly little scene in a game that was supposed to be about rhythm, fitness and quiet tactical tweaks. Instead, it underlined the raw edge around this new regime. Passion is welcome; red mist less so.

A 3-3 draw that answered few questions

On the pitch, the match itself swung wildly. Chelsea found their way to goal through Delap’s composure from the penalty spot, but every step forward seemed to come with a stumble at the back. The 3-3 draw felt less like a pre-season tune-up and more like a live demonstration of the work still to be done.

Defensive lapses kept dragging the team into trouble, exposing the very flaws Alonso is trying to iron out. With his back line already stretched and his depth eroding in real time, those gaps looked even more alarming.

By the final whistle, the scoreline felt secondary. The real story lay in the players missing and the ones limping.

A revolution tested early

As the squad prepares to fly back to Stamford Bridge, attention turns not to video analysis but to scan results and medical reports. Alonso has been hired to drag Chelsea back into the Champions League places, to impose structure and authority on a club that has lurched from one rebuild to the next.

That project has barely begun, and already it is under strain. Two young defenders sidelined, transfer funds tight, defensive frailties laid bare in a chaotic draw thousands of miles from home.

Pre-season is supposed to offer clarity. For Chelsea, it has delivered a harsher question: how do you launch a defensive reset when the very foundations keep breaking beneath you?
