Chelsea's preseason woes deepened with a 4-1 loss to Celtic, raising concerns about the team's defensive vulnerabilities and tactical implementation under new manager Enzo Maresca. Key players like Benoit Badiashile and Wesley Fofana faced criticism for poor performances, with Badiashile earning the lowest player rating for a crucial mistake leading to a Celtic goal. Chelsea's high defensive line was exploited repeatedly, allowing Celtic to capitalize on their transitions, indicating significant areas for improvement. While some players showed promise, the overall performance left fans frustrated, with one even lamenting the club's spending on underwhelming talent. Despite the criticism, Maresca emphasized the need for patience as he integrates his system, with more preseason matches ahead to assess player roles. The loss serves as a wake-up call for Chelsea as they gear up for a challenging season ahead.
