In the letter, Diomande recalled the day he received the devastating news about his sister's death. He remembered picking up a call from home and being told that his sister had died after being poisoned at a party. He was just 15 years old at the time and was left with many unanswered questions. He wrote, "I never got any answers. I don't know if I want to know why. Maybe it was jealousy. Maybe it's just something that happens in our country. Maybe I could have protected you. I don't know."

Diomande, who is now 19 and one of the most sought-after young talents in football, is still grappling with the loss of his sister. His debut season with German club RB Leipzig was a stunning success, but the emotional pain of losing his sister will likely weigh heavily on him throughout his career.
