William Saliba faces 4-5 month layoff after World Cup collapse

William Saliba will miss four to five months of Arsenal action after collapsing during France’s World Cup semi-final on 18 June 2026.

What happened to William Saliba?

Saliba, 25, crumpled to the turf in obvious distress during Les Bleus’ 1-0 defeat to Spain in the World Cup semi-finals. He told Dayot Upamecano, his France defensive partner, that his back felt “dead” and the pain was unbearable. Sources say Saliba played through months of chronic back pain, masking it with painkillers and a light training plan. France’s medical staff followed Arsenal’s protocols, but Didier Deschamps, then France manager, may not have been fully briefed on the severity.

Why it matters for William Saliba

The injury ends Saliba’s season just as Arsenal prepare for a new campaign. Gunners staff expect him back between November and December 2026, depending on recovery from likely surgery. Without him, Arsenal’s defensive reshuffle gains urgency ahead of Premier League and Champions League fixtures. Saliba’s absence also complicates France’s rebuild under a new manager after Deschamps’ exit.

How Saliba reached this point

For months Saliba managed back pain with medication and modified sessions. Reports suggest he pushed through discomfort in training and matches, masking the issue from public view. France’s medical team mirrored Arsenal’s cautious approach, yet the toll became too much during the high-pressure semi-final. The episode exposed the fine line between toughness and long-term risk in modern football.

What comes next for Saliba and Arsenal

Surgery is the probable fix, with a four-to-five-month recovery window. Arsenal’s recruitment team has already begun informal talks on defensive reinforcements. Saliba’s return will hinge on rehab discipline and avoiding setbacks. For now, the Gunners must navigate pre-season and early league games without their French star.
