Arsenal face the prospect of being without William Saliba for a significant period after the French defender's chronic back problems finally reached breaking point during Tuesday's World Cup semi-final against Spain.
The 25-year-old centre back crumpled to the ground in pain during the clash between Les Bleus and Spain, reportedly telling defensive partner Dayot Upamecano: "I can't take it anymore. My back is dead."
The moment laid bare what has been a hidden battle for Saliba, who has reportedly been managing persistent back pain for months through painkillers and a reduced training regime at both Arsenal and with the France national team.
French outlet L'Equipe reports that surgery is now considered the most likely course of action for the defender, which would rule him out for a large portion of next season.
Arsenal are understood to be preparing for a four-to-five month absence and may look to the transfer market to bring in cover during what promises to be a challenging spell without one of their key defensive figures.
