Mike Penders has just exposed Chelsea’s biggest problem, and it’s very worrying

Goalkeeper Mike Penders admitted Chelsea struggled against Sunderland's physical approach and defensive block following a Premier League defeat at the Stadium of Light. Speaking to the club's website, Penders highlighted how Regis Le Bris' side disrupted Chelsea's build-up play through aggressive pressing before defending deep with every player behind the ball.

Writer Leah Jones argues that the defeat exposes a worrying tactical vulnerability for manager Xabi Alonso. The article contends that future opponents now have a blueprint to frustrate Chelsea, leaving Alonso tasked with finding solutions against disciplined, physical sides.
