A professional footballer has told of the mental toll his time on the sidelines took in the hope it would help to break a "dog-eat-dog" culture in the sport.
Jayden St Paul, 20, announced he would be leaving Norwich City FC on Monday.
He said a knee injury had plagued him for almost two years before he made the "tragic" decision to hang up his boots.
"The scariest thing throughout this process was admitting I wasn't OK," Jayden, from Uxbridge, London, said.
The goalkeeper, who played for the Canaries' academy side, had signed a year-long extension to his contract - despite his injury - due to the promise he had shown.
