Crystal Palace supporter Ollie Thomas has called for a tactical change after Sunday's heavy defeat by Brighton, arguing that the team's defensive problems must be addressed quickly.

Thomas believes the current setup leaves Palace too exposed at the back. In his view, the club's back five has not looked ready for the demands placed on it, while the summer recruitment has also failed to strengthen that area sufficiently.

His proposed solution is to move away from a back-three system and add an extra midfielder, with the aim of giving Palace greater protection in front of the defence. He questioned why the team's most vulnerable area continues to be exposed during matches.

Thomas warned that Palace could become involved in a relegation battle if the defensive issues remain unresolved. The wider question for the club is whether the formation is the main cause of the problems, or whether changes in other areas are also required.
