Arsenal will assess William Saliba’s back injury when he returns to the club after his World Cup appearance.
The France centre-back has been plagued by back problems for several weeks and carried the problem into the World Cup.
The problem appeared to escalate during France’s semi-final defeat to Spain when he was forced off the field after just 30 minutes.
Surgery is among the options the Gunners will consider when he returns to London, although the operation is likely to require a long layoff to recover.
The 25-year-old made 50 appearances in all competitions for Arsenal last season, ending a 22-year wait to win the Premier League and reaching the Champions League final.
Earlier at the World Championships, Saliba said: “I had a bit of trouble for a few months.
“I gritted my teeth because there was the Champions League and the Premier League.
“The World Cup only happens every four years, so you have to bite the bullet.”
He missed France’s final group game against Norway before returning to Didier Deschamps’ side for the knockout stages.
France play England in the third place play-off on Saturday (22:00 BST).
