Chelsea's Pre-Season Nightmare: Injuries and Chaos

Aaron Anselmino’s anguished walk to the touchline told Chelsea everything they didn’t want to hear about their summer.

No scans. No medical bulletins. Just the image of a 21-year-old centre-back in tears, limping off after 29 minutes at Stadium Sultan Ibrahim, clutching at his hamstring and his face buried in his shirt. For a club banking on youth, it felt like a gut punch.

A nightmare afternoon at the back

This was supposed to be a gentle tune-up in Johor. Instead, it turned into a pre-season horror reel for Enzo Maresca’s defensive plans.

The problems started before a ball was kicked. Mamadou Sarr, 20 years old and pencilled in to start, pulled out during the warm-up. One moment he was in the XI, the next he was heading down the tunnel, leaving Chelsea a centre-back short before the referee had even checked his watch.

Then came Anselmino.

Signed in 2024 and still trying to shake off the “promising but fragile” tag, the former Borussia Dortmund and Strasbourg loanee went down just before the half-hour mark. He stayed there, flat on the turf, treatment team around him, anger etched across his face. When he finally rose, it was to leave the pitch in tears, team-mates closing in to console him.

For a player whose time at Stamford Bridge has already been punctured by similar muscle issues, the emotion was understandable. This wasn’t just another tweak. It looked like the fear of another chapter lost to the treatment room, another season slipping away before it starts.

For Maresca, it rips up a key part of his early blueprint. With transfer funds said to be tight after heavy spending in other areas, the new head coach had been expected to lean on his young centre-backs to carry the load. In one sweltering Malaysian afternoon, he saw two of them disappear from his immediate plans.

Touchline tempers flare

The chaos wasn’t confined to the pitch.

A reckless challenge on Liam Delap lit the fuse on the touchline, dragging Chelsea’s new-look coaching staff into the spotlight for all the wrong reasons. Set-piece specialist Austin MacPhee, brought in as part of the backroom overhaul, reacted furiously and had to be physically held back by Maresca as tempers flared with the opposition bench.

It was a flashpoint that underlined the edge around this Chelsea project. The staff are clearly invested, emotional, on the line with their players. But in a pre-season friendly, with bodies already falling, it added another layer of unease to an already fraught evening.

Goals, gaps and growing pains

On the scoreboard, a 3-3 draw might look like entertainment. In reality, it was a messy, erratic contest that shone a harsh light on where Chelsea stand.

Delap’s composure from the spot offered one of the few clean positives, his penalties giving the attack something to cling to. They found ways to hurt the hosts, carved out chances, and showed flashes of the vertical, aggressive football Maresca wants.

At the other end, the picture was far less kind. Defensive lapses, loose positioning, and a lack of cohesion turned what should have been a routine exercise into a tactical stress test. With Sarr missing and Anselmino gone before half-time, the back line looked exactly what it was: patched together and uncertain.

These are the teething problems a new coach expects. What he cannot afford is to lose the very players he was counting on to grow through them.

Stamford Bridge awaits – and so does the treatment room

As the squad heads back to London, the narrative around Chelsea’s pre-season shifts sharply. The focus is no longer on patterns of play or pressing triggers. It’s on scan results, rehabilitation schedules and whether the club can ride out another injury storm without ripping up its long-term plan.

Maresca has been hired to drag Chelsea back into the Champions League places, to turn a collection of expensive prospects into a coherent, ruthless side. That task was daunting enough when everyone was fit.

Now, before a competitive ball has been kicked, his revolution is already being asked the hardest question in football: can a team built on youth withstand this much adversity and still grow fast enough to meet the club’s demands?
