For the past two years, Bukayo Saka has helped to fund 120 operations for children in Nigeria.
To say thanks, the children whose lives have been transformed have written letters to Saka.
"It makes me smile. These kind of things mean more than anything in the world," Saka says while opening them in the latest episode of Fan Mail.
Saka has been supporting the children's medical charity, BigShoe, to help children from Kano in the African country of Nigeria, where both of his parents were born.
"I am really proud of my Nigerian heritage so to be able to support the children out there is really special for me and I feel so blessed to be able to help them," Saka, still just 22 years of age himself, explains.
“I remember being their age with big, big dreams. The message I want to send to them is to keep dreaming, keep believing and go for it.”
'You've given children brand new life'
Saka also received a letter from a doctor who has performed many of the surgeries, including one on 12-year-old Kabir, who was struggling to walk.
"Your support has given the children brand new life," he says. “Before Kabir’s surgery, he was barely able to walk. He is now able to play the game he loves, post-recovery. His friends even call him “Saka” - and this makes him really proud."
