Sengalese striker, Nicolas Jackson has responded sharply to former Chelsea player John Obi Mikel following Chelsea's 6-2 victory over Wolves.
The win came after a disappointing start to the season, which included a loss to Manchester City.
Mikel had criticised Jackson for missing key opportunities in the City match, questioning the team's direction under new manager Enzo Maresca.
Jackson, who has been the butt of criticism due to his inconsistent finishing since joining Chelsea from Villarreal, made a strong comeback by scoring Chelsea's opening goal against Wolves.
After the match, Jackson took to Instagram to respond to Mikel's criticism, telling him to "shut your mouth" while emphasising how much work he had been putting in.
"'Shut your mouth don't talk s***, we are killing ourselves for Africa," he wrote.
