Chelsea travel to Paris on Wednesday night for the Champions League last-16 first leg against Paris Saint-Germain, but the mood at Cobham has turned grim. What was supposed to be a moment of hope has instead delivered a crushing blow to Liam Rosenior’s side. The game represents the Blues’ biggest test under the new boss — and they are heading into it crippled by fresh injury setbacks that could derail their entire season.

Rosenior has rotated his squad carefully through a congested fixture list, resting key players during Saturday’s FA Cup win over Wrexham. Cole Palmer, Enzo Fernandez and Moises Caicedo were all left behind to stay fresh for the Parc des Princes. But Tuesday’s training session delivered the nightmare update no Chelsea fan wanted to see.
The Update From Chelsea Training Levi Colwill was spotted back with the first team on Tuesday for the first time this season, sparking wild excitement among supporters. Photos showed the defender working alongside his teammates, and he even posted on Instagram with the caption “Back with the boys.” For a split second, it looked like the long-awaited return was imminent.
It wasn’t.
Simon Johnson of The Athletic quickly poured cold water on the euphoria. While Colwill’s presence was a step forward, the timeline has not changed at all. This was not a breakthrough session — he has been doing controlled group work for some time behind the scenes. A full return to competitive action remains weeks away at the earliest. Chelsea are still only “targeting” a comeback before the season ends, provided the final stages of rehabilitation go perfectly.
Colwill hasn’t played a single minute since July. A torn ACL suffered in August training has wiped out his entire campaign. All 42 matches this season have been without him — and the timing couldn’t be worse.
Reece James was also seen in training after worrying fans when he was missing from Monday’s limited photos, but his situation remains fragile. The right-back has been a constant injury concern all year.

What the Timeline Actually Shows The reality is brutal. Chelsea’s defensive crisis has been the story of the season, with countless centre-back partnerships failing to deliver any consistency. Colwill was emerging as one of the most reliable performers before his injury — and his continued absence is now being described privately as a “disaster” inside the club.
Nine Premier League games remain, but the bigger picture is the Champions League. Whether Colwill features in any of them is suddenly in serious doubt.
What Awaits in Paris The timing of this update could not be more painful. PSG boss Luis Enrique is already under pressure after losing seven times this season, including four defeats in 2026, and their Ligue 1 lead has shrunk to just one point following Friday’s 3-1 home collapse against Monaco.
Chelsea were hoping to arrive in Paris with momentum and a near-full squad. Instead, they travel with major defensive holes. Joao Pedro has been in sensational form under Rosenior — nine goals and five assists in two months, including a hat-trick against Aston Villa and another goal versus Wrexham. He also scored in last season’s Club World Cup final win over PSG and will be expected to carry the attack again.
Cole Palmer has rediscovered his spark too, with six goals in nine games since Rosenior took charge. But even their brilliance may not be enough to paper over the cracks at the back.
Worse still, Estevao remains sidelined with the hamstring injury that has kept him out for nearly a month and did not travel with the squad. Jamie Gittens is also unavailable.
The objective for Wednesday is now survival. PSG may be vulnerable, but Chelsea cannot afford to overextend with their defence in such disarray. A heavy defeat in the first leg would leave Rosenior facing an impossible task in the return fixture at Stamford Bridge.
Final Word for Chelsea What began as hopeful training pictures has turned into the worst possible news ahead of the club’s toughest night of the season. Levi Colwill’s return is still weeks away, Reece James remains a fitness worry, and key attacking options are missing. Chelsea’s defensive problems have been laid bare once again at the worst possible moment.
PSG are the defending European champions. Chelsea have beaten them before — but never with a backline this depleted. Wednesday night in Paris just became a whole lot more dangerous for the Blues.
All eyes on Paris… but the real story is the disaster unfolding in London.
