Arsenal vs Chelsea: Injury Updates and Team News Ahead of London Derby
Mikel Arteta will take an unbeaten Arsenal into a London derby with Chelsea on Sunday with one eye on the league table and the other on the treatment room.
Both sides have started the Premier League season with two wins from two. The margins at the top are already fine. So every body available counts.
Mosquera scare eased, but wait goes on
Cristhian Mosquera’s early withdrawal in the 1-0 win at Aston Villa raised alarms, but Arteta moved to calm them.
The defender started at Villa Park before being replaced by Ezri Konsa, prompting fears of a hamstring problem. Arteta framed it as caution rather than crisis.
“He was more a precaution than anything else,” the Arsenal manager said, making clear the club will use Saturday’s session to judge whether Mosquera can be involved against Chelsea.
He was not among those pictured in training at London Colney on Thursday, which underlined the uncertainty, but not necessarily a setback. Arsenal will push the decision as late as they dare.
Timber edging back into view
If Mosquera is a short-term concern, Jurrien Timber is the slow-burning positive.
The full-back has yet to play a competitive minute this season after a minor groin procedure in the summer. His absence has forced Arteta to reshuffle, but the Dutchman is finally edging back toward the matchday squad.
Timber was seen in light training on Thursday, and Arteta’s update hinted at a possible, if slim, inclusion against Chelsea.
“Yeah, he’s in really good condition at the moment,” Arteta said. “He’s been now a few weeks on the pitch and he’s been training with us now, so he’s in a good place.”
That “good place” might not yet mean a start, or even guaranteed minutes, but just having Timber on the bench for a fixture of this intensity would be a significant boost.
Guimaraes knock clouds midfield picture
The picture is less clear around Bruno Guimaraes.
The Brazilian took another knock in the win at Villa, adding to the problem that had already ruled him out of the opening 3-0 victory over Coventry City after the Community Shield rout of Manchester City.
“Yeah, he had a knock against Villa in the previous game and he’s been assessed,” Arteta said. “Hopefully tomorrow he will be okay for training.”
Like Mosquera, Guimaraes was not seen in Thursday’s training images. With Chelsea’s midfield likely to test Arsenal’s control and intensity, his availability could shape Arteta’s approach.
Saliba’s registration hints at earlier return
One of the more intriguing developments came off the pitch. William Saliba has been named in both Arsenal’s 25-man Premier League squad and their Champions League group-stage list.
Given the seriousness of the back injury he suffered at the World Cup, that decision suggests cautious optimism that the centre-back could return before January, when squads are resubmitted.
Arteta stressed the complexity of the recovery.
“Yes, we don’t really know the amount of weeks he’s going to be out because it’s about a healing process in the beginning, it’s a bit different,” he explained. “We know that we have to respect certain timings. The progression has been really positive in the last few weeks, but we need to wait and see how that one reaction will start to put a lot into it.”
No firm dates. No guarantees. But the door to 2024 without Saliba has quietly been nudged back open.
Perfect starts on the line
Arsenal and Chelsea stand among only four Premier League clubs with perfect records after two games. Something has to give at the Emirates.
Last season, the rivalry tilted sharply Arsenal’s way. Across four meetings in all competitions, the Gunners won three and drew the other, imposing both their style and their will on Chelsea.
This time, the stakes are different. Early-season momentum, squad depth under strain, and the psychological weight of maintaining a flawless start all converge on Sunday.
Arteta’s message is clear: manage the risks, trust the process, and get enough of his key men on the pitch to keep that 100 per cent record intact.
