Charly Musonda has been promoted to the Chelsea academy as a full-time scholar.
The teenage Belgian is regarded among the best young talents in Europe.
Chelsea Academy manager Jim Fraser told the club's website: "Also known as Charly Junior, with Charly being his father's name, Mus is the younger brother of Lamisha and Tika who are Chelsea Under-21 players. He signed for us last season after joining from Anderlecht. Mus is a Belgian U17 international who plays anywhere in midfield and is an exciting, technical player. Again he is a scorer and a creator of goals."
