William Saliba is unlikely to make Arsenal's Premier League clash with Southampton due to injury, football.london understands.
The French international has been sidelined for nearly a month after being forced off during the Gunners' Europa League defeat to Sporting CP with a back injury. It is understood that this was an aggravation of a problem he picked up in the 3-0 victory over Fulham four days prior.
Arsenal were given a minor boost after Saliba was pictured on a training bicycle with fellow long-term absentee Mohamed Elneny on Tuesday. Despite that though, he remains unlikely to make Friday's clash with Southampton, although the Gunners are thought to be assessing the issue on a daily basis.
