The Welsh club wasted little time taking a swipe at the Saints, who were dramatically expelled from last season’s play-offs after being found guilty of obtaining insider information on rivals.
With the sides set to meet in September, Wrexham shared their fixture graphic on social media alongside a magnifying glass and spy emoji, an apparent reference to the controversy.
The post quickly gained traction among supporters.
The jokes did not end there. Wrexham also included a calendar reminder to "check training ground" two days before facing Southampton, while eagle-eyed fans noticed the Saints’ badge had been edited to feature a silhouette hiding behind a tree.
The image referenced the leaked footage of an intern allegedly spying on Middlesbrough’s training sessions, a key moment in the scandal that dominated last season’s Championship.
