Arsenal’s worst fears have been confirmed. William Saliba needs back surgery and could miss four to five months of action, according to L’Equipe. That timeline would keep the 25-year-old sidelined until late 2026 or even early 2027.
It’s a brutal blow for Mikel Arteta. And it couldn’t have come at a worse time.
How did the injury happen?
Saliba went down in the 30th minute of France’s World Cup semi-final against Spain on Tuesday. There was no tackle. No collision. He simply crumpled to the ground while jogging with the ball.
Lip readers picked up what he told teammates on the pitch. According to the Daily Mail, he said his back was “gone.” Get French Football News reported that he told defensive partner Dayot Upamecano he couldn’t bear the pain any longer.
He was replaced by Crystal Palace’s Maxence Lacroix. France went on to lose 2-0.
Here’s the thing — this wasn’t a sudden injury. Saliba had been managing chronic back pain for months. He played through it during Arsenal’s Premier League title run. He gritted his teeth through 120 minutes of the Champions League final defeat to PSG. And he pushed on into the World Cup.
During the group stage, Saliba himself admitted to the struggle. He acknowledged having dealt with persistent niggles for several months but said he’d kept going because of what was at stake. He also noted the World Cup only comes around every four years, so he felt he had to push through.
Reports from France indicate he wasn’t even training between World Cup matches. He was simply showing up to play and relying on painkillers and a carefully managed routine.
Eventually, his body said enough.
What does this mean for Arsenal’s 2026-27 season?
The numbers paint a grim picture. A four-to-five-month absence means Saliba would miss:
- The Community Shield on August 16
- The opening weeks — possibly months — of the Premier League season
- Early Champions League group stage matches
- A potential return no earlier than November or December 2026
Arsenal won the league last season largely because of their defensive record. Saliba was at the heart of that, making 50 appearances across all competitions. Losing him isn’t just about losing a centre-back — it’s about losing the player who organises the entire backline.
Gabriel Magalhaes is a fine defender, but he’s looked more error-prone when asked to shoulder added responsibility without Saliba beside him. That vulnerability could cost points in tight games.
Arteta does have options. Ben White, Jurrien Timber, Piero Hincapie, and Riccardo Calafiori can all slot in at centre-back. None of them, though, offer the same ball-playing quality or channel-defending ability that Saliba provides.
Will Arsenal buy a replacement?
That’s the big question. And it’s complicated.
Arsenal have reportedly already started sounding out centre-back targets. According to Arsenal Insider, the club has been tracking Maxence Lacroix and Ezri Konsa as potential reinforcements. The fact they were doing this before the World Cup ended tells you how seriously they’ve been taking the situation behind the scenes.
But finances could be a stumbling block. The Gunners are reportedly chasing Morgan Rogers, who could cost around £130 million. Bradley Barcola has also been linked at a fee north of £100 million. Spending that kind of money up front while also bringing in a centre-back would stretch even Arsenal’s resources.
There’s also the question of whether any available centre-back actually moves the needle. A short-term fix who doesn’t improve the squad long-term may not appeal to Arteta or the club’s recruitment team.
This isn’t Arsenal’s first rodeo with Saliba’s back, either. He missed around three months during the 2022-23 season with a similar problem. That experience will inform how cautiously they approach his recovery this time around.
For now, Arsenal fans are left holding their breath. The title defence was always going to be a fight. Without their best defender for the first chunk of the season, it just became significantly tougher.
