An organisation called Provision gives youngsters the opportunity to become the stars of the future. Kingsley Williams was taking part in a competition in Spain and he caught the eye of the Blades so Blackwell has snapped him up.
Players who attend the Provision courses are trained twice a week by professional coaches. The Blades aren't the only interested club in players at the course as Burnley and Blackburn Rovers look to do the same thing.
Williams who did attend a brief spell at the age of 10 at United is delighted to get a rare second opportunity. He said: "I want to come to Sheffield United and work hard whilst trying to impress. I am confident of showing what I can do and ultimately my aim is to become a professional footballer and play for England.
