Arsenal faced a concerning moment during their match against Crystal Palace at Emirates Stadium on Sunday, as key defender William Saliba was substituted at half-time. The French centre-back, a cornerstone of Arsenal’s formidable defensive unit, was replaced by Cristhian Mosquera, leaving fans and manager Mikel Arteta anxious about a potential injury. While it remains unclear whether Saliba’s withdrawal was due to an injury or a tactical decision, Arteta will be desperate to avoid losing one of his star players, especially with a packed schedule ahead.

The first half saw Crystal Palace take the lead through Eberechi Eze, who scored against his former club. Eze capitalised on a Declan Rice free-kick that fell to him, calmly guiding the ball into the corner on the half-volley to put the home side ahead. Arsenal, however, showed resilience, but Saliba’s exit at the break cast a shadow over their performance.
Saliba’s potential injury adds to existing concerns within Arsenal’s defensive ranks. Going into the match, there were doubts over the fitness of Gabriel Magalhaes, Saliba’s regular defensive partner. Gabriel had picked up a knock during Arsenal’s commanding 4-0 victory over Atletico Madrid in midweek and missed several training sessions leading up to the Palace clash. Despite these concerns, the Brazilian was deemed fit to start, underscoring his importance to the team. Together, Gabriel and Saliba have forged a robust partnership that has been instrumental in Arsenal’s strong start to the season, with Saliba already featuring in 10 matches this campaign.
The uncertainty surrounding Saliba’s condition raises questions about his availability for Arsenal’s upcoming Carabao Cup match against Brighton on Wednesday. Arteta is expected to provide an update on the 24-year-old’s status in his post-match press conference following the Crystal Palace game. Arsenal fans will be hoping for positive news, as Saliba’s presence has been vital to the team’s defensive solidity and their push for the Premier League title.
Adding to the context of the match, Arsenal received a significant boost in their title aspirations on Saturday when rivals Liverpool suffered a surprising 3-2 defeat to Brentford. The result left Liverpool languishing in sixth place, four points behind Arsenal before the Gunners’ clash with Palace. Liverpool manager Arne Slot expressed his frustration after the game, stating, “Disappointing, again. I was hoping for and expecting a better performance. It was far from what we are used to. Teams seem to have a certain playing style against us, which is a very good strategy to play, and we haven’t found an answer yet.”
Slot also acknowledged the challenges his team has faced following significant changes in the summer, noting, “If you change quite a lot during the summer, then I think it’s not a surprise that it can go a bit like this. But I didn’t expect it to go with four losses in a row, let that be clear.” Liverpool’s struggles have opened the door for Arsenal to capitalise, but Arteta will know that maintaining a fully fit squad, particularly his defensive stalwarts, will be crucial to sustaining their title challenge.
As Arsenal navigate this critical period, all eyes will be on Arteta’s update regarding Saliba’s condition. The Gunners’ depth will be tested if the Frenchman is sidelined, but with players like Mosquera stepping up, Arteta will hope his squad can adapt and maintain their momentum in the race for Premier League glory.
