The Emirates Stadium has seen low attendances for the past four league games — a trend that is likely to continue for the remaining two home matches this season.
And Sportsmail understands the no-shows are causing serious concern among the Gunners hierarchy.
Many of the thousands of regulars who have decided against turning up are season-ticket holders, so financially — at least in the short-term — the empty seats are not having a significantly detrimental impact.
However, there are fears the no-shows will have a knock-on effect on the club’s commercial value. It also underlines the growing apathy towards the team under Wenger, whose job is under threat, with certain figures at the club believing he must leave before next season.
While the Gunners are still in with a chance of Europa League glory, the team could finish seventh behind Burnley, who can leapfrog Wenger’s side into sixth by beating Chelsea on Thursday.
And Arsenal’s summer plans could be hit if they come seventh. The club are set to confirm plans to tour Singapore, with their first game — potentially against Atletico Madrid — pencilled in for July 26.
However, a seventh-place finish could mean they would need to play in the Europa League second qualifying round during the tour, leaving them with an issue over which players to take to Asia.
