Chelsea Football Club has issued a warning to its staff regarding the use of Fantasy Premier League (FPL) and the potential for inadvertently revealing sensitive team news. The caution comes after an incident where information about a player's injury appeared to have been disclosed through FPL team selections.

Reports indicate that the injury status of a player became apparent through the fantasy team choices made by staff. This has prompted the club to remind employees about the importance of discretion when participating in the popular online game, which allows managers to pick real-life players for their virtual squads. Changes in player availability for FPL often reflect their fitness and likelihood of playing in upcoming matches. The incident highlights a potential security vulnerability, even in a seemingly innocuous context like a fantasy sports game.
