Arsenal manager Mikel Arteta revealed the club has not set a timescale on Gabriel Jesus' return from injury.
Brazil striker Jesus has been an ever-present in the league for Arteta's side, scoring five goals. He is not expected to be available for the Gunners immediately after the World Cup, though, thanks to an injury sustained on international duty.
Arsenal sit five points clear at the top of the Premier League, with Jesus' former club Manchester City their closest challengers.
