William Saliba limped off during Arsenal's Europa League last-16 second leg defeat against Sporting Lisbon. But his recovery process is not going as the Gunners had hoped.
The 22-year-old is a key player for the squad but the Arsenal boss cannot count on him yet: "He hasn’t improved this week at all," Arteta told reporters on Monday.
The Frenchman's absence has been a huge setback in their hunt for the Premier League title. As a result, the board are considering signing a replacement for Saliba in the next transfer window.
According to the 'Daily Mail', the Gunners are targeting Crystal Palace centre-back Marc Guehi for next campaign. His current contract expires in 2026 but his future could change dramatically if he receives an offer from Arsenal.
