Chelsea forward Nicolas Jackson has sharply responded to criticism from club legend John Obi Mikel following Chelsea's 6-2 victory over Wolverhampton Wanderers. Jackson, who scored the opening goal within 98 seconds and assisted another, took to Instagram to tell Mikel to 'shut your mouth' in reaction to previous comments criticizing his finishing. Mikel had questioned Jackson's proficiency in the final third after Chelsea's 2-0 defeat to Manchester City, suggesting the team needed a more reliable striker akin to Erling Haaland. Despite Jackson's inconsistent performances since joining Chelsea, he has managed 18 goals and 17 assists in 46 appearances. The contentious exchange underscores the scrutiny Jackson faces as he attempts to cement his role as Chelsea's main striker under new manager Enzo Maresca.
